Book excerpt: A new type of adaptive optics (AO) based on the principles of digital holography (DH) is proposed and developed for the use in wide-field and confocal retinal imaging. Digital holographic adaptive optics (DHAO) dispenses with the wavefront sensor and wavefront corrector of the conventional AO system. DH is an emergent imaging technology that gives direct numerical access to the phase of the optical field, thus allowing precise control and manipulation of the optical field. Incorporation of DH in an ophthalmic imaging system can lead to versatile imaging capabilities at substantially reduced complexity and cost of the instrument. A typical conventional AO system includes several critical hardware pieces: spatial light modulator, lenslet array, and a second CCD camera in addition to the camera for imaging. The proposed DHAO system replaces these hardware components with numerical processing for wavefront measurement and compensation of aberration through the principles of DH. We first design an image plane DHAO system which is basically simulating the process the conventional AO system and replacing the hardware pieces and complicated control procedures by DH and related numerical processing. In this original DHAO system, CCD is put at the image plane of the pupil plane of the eye lens. The image of the aberration is obtained by a digital hologram or guide star hologram. The full optical field is captured by a second digital hologram. Because CCD is not at the conjugate plane of the sample, a numerical propagation is necessary to find the image of the sample after the numerical aberration compensation at the CCD plane. The theory, simulations and experiments using an eye model have clearly demonstrated the effectiveness of the DHAO. This original DHAO system is described in Chapter 2.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents not only the simultaneous combination of optical methods based on holographic principles for marker-free imaging, real-time trapping, identification and tracking of micro objects, but also the application of substantial low coherent light sources and non-diffractive beams. It first provides an overview of digital holographic microscopy (DHM) and holographic optical tweezers as well as non-diffracting beam types for minimal-invasive, real-time and marker-free imaging as well as manipulation of micro and nano objects. It then investigates the design concepts for the optical layout of holographic optical tweezers (HOTs) and their optimization using optical simulations and experimental methods. In a further part, the book characterizes the corresponding system modules that allow the addition of HOTs to commercial microscopes with regard to stability and diffraction efficiency. Further, based on experiments and microfluidic applications, it demonstrates the functionality of the combined setup, and discusses several types of non-diffracting beams and their application in optical manipulation. The book shows that holographic optical tweezers, including several non-diffracting beam types like Mathieu beams, combined parabolic and Airy beams, not only open up the possibility of generating efficient multiple dynamic traps for micro and nano particles with forces in the pico and nano newton range, but also the opportunity to exert optical torque with special beams like Bessel beams, which can facilitate the movement and rotation of particles by generating microfluidic flows. The last part discusses the potential use of a slightly modified DHM-HOT-system to explore the functionality of direct laser writing based on a two photon absorption process in a negative photoresist with a continuous wave laser

Available in PDF, EPUB and Kindle. Book excerpt: This book is unique in covering most of the developments on optical holographic techniques since holography’s invention in 1947 by Dennis Gabor. Starting from conventional holography with photopolymer recording techniques to CCD(Charge Coupled Device)-based digital holography, this book covers the spectrum of contemporary holographic techniques. The first chapter deals with conventional holographic methods using photographic plates in both in-line Gabor holography and off-axis holography. Then the second chapter covers principle and experimental techniques of the Conoscopic holography technique, and the third chapter deals with Computer generated holography. The fourth chapter discusses basic principles of dynamic holography using photorefractive crystals where the theory and experiments show how the photorefractive effect is used for dynamic recording of holograms. The fifth and sixth chapters extensively discuss the fundamentals of digital holography and unconventional coherence holography. In digital holography, two types of phase shifting methods which are dynamic and geometric phase shifting digital holographic techniques are elaborated with practical examples. Then, in the sixth chapter, the unconventional coherence holographic method describes a new holography using incoherent light sources. This book is intended for advanced undergraduate and first-year graduate-level students, as well as researchers looking for a complete resource in holography techniques.

Book excerpt: Holoscopy is a new tomographic imaging modality that combines techniques of digital holography with Fourier-domain optical coherence tomography (FD-OCT). Dierck Hillmann gives a theoretical introduction to the mathematics and physics of holoscopy and develops an efficient numerical reconstruction procedure. Compared to FD-OCT, holoscopy provides unique advantages by enabling tomographic imaging without a limited depth of focus, but results in an increased numerical cost for reconstruction. In further chapters, the author introduces techniques for FD-OCT that are relevant to holoscopy as well. He demonstrates and compares numerical reconstruction methods for FD-OCT and shows how motion and dispersion artifacts in FD-OCT can be numerically compensated.

Book excerpt: Science Study Series No. 39: Lasers and Holography: An Introduction to Coherent Optics focuses on the processes, methodologies, and techniques involved in optics, including wave diffraction and patterns, zone plates, holograms, and diffraction. The publication first ponders on holograms as wave patterns, coherence, and lasers. Topics include reflectors and resonators, natural line width, semiconductor lasers, reflectors and spatial coherence, energy conservation with reflectors, frequency coherence and stability, coherent waves from small sources, photographic grating, and properties of waves. The book then tackles wave diffraction, as well as diffraction by two and multiple slits, near field, multiple slit gratings and photographic gratings, refraction by prisms, dependence of diffraction on wavelength, and disks and zone plates. The manuscript reviews the properties of holograms and zone plates. Discussions focus on holograms and coherent radar, single wavelength nature of holograms, image inversion, reconstruction with a small portion of a hologram, pseudoscopy in the real image of a hologram, zone plates as negative lenses, offset zone plates, and zone plates with areas interchanged. The text is a dependable reference for researchers interested in coherent optics.

Available in PDF, EPUB and Kindle. Book excerpt: Since the advent of the laser, coherent optics has developed at an ever increasing pace. There is no doubt about the reason. Coherent light, with its properties so different from the light we are surrounded by, lends itself to numerous applications in science, technology, and life. The bandwidth of coherent optics reaches from holography and interferometry, with its gravitational wave detectors, to the CD player for music, movies, and computers; from the laser scalpel, which allows surgical cutting in the interior of the eye without destruction of the layers penetrated in front of it, to optical information and data processing with its great impact on society. According to its importance, the foundations of coherent optics should be conveyed to students of natural sciences as early as possible to better prepare them for their future careers as physicists or engineers. The present book tries to serve this need: to promote the foundations of coherent optics. Special attention is paid to a thorough presentation of the fundamentals. This should enable the reader to follow the contemporary literature from a firm basis. The wealth of material, of course, makes necessary a restriction of the topics included. Therefore, from the main areas of optics, wave optics and the classical description oflight is given most ofthe space available. The book starts with a quick trip through the history of physics from the viewpoint of optics.

Available in PDF, EPUB and Kindle. Book excerpt: Leading experts present the latest technology and applications in adaptive optics for vision science Featuring contributions from the foremost researchers in the field, Adaptive Optics for Vision Science is the first book devoted entirely to providing the fundamentals of adaptive optics along with its practical applications in vision science. The material for this book stems from collaborations fostered by the Center for Adaptive Optics, a consortium of more than thirty universities, government laboratories, and corporations. Although the book is written primarily for researchers in vision science and ophthalmology, the field of adaptive optics has strong roots in astronomy. Researchers in both fields share this technology and, for this reason, the book includes chapters by both astronomers and vision scientists. Following the introduction, chapters are divided into the following sections: * Wavefront Measurement and Correction * Retinal Imaging Applications * Vision Correction Applications * Design Examples Readers will discover the remarkable proliferation of new applications of wavefront-related technologies developed for the human eye. For example, the book explores how wavefront sensors offer the promise of a new generation of vision correction methods that can deal with higher order aberrations beyond defocus and astigmatism, and how adaptive optics can produce images of the living retina with unprecedented resolution. An appendix includes the Optical Society of America's Standards for Reporting Optical Aberrations. A glossary of terms and a symbol table are also included. Adaptive Optics for Vision Science arms engineers, scientists, clinicians, and students with the basic concepts, engineering tools, and techniques needed to master adaptive optics applications in vision science and ophthalmology. Moreover, readers will discover the latest thinking and findings from the leading innovators in the field.
