Book excerpt: Polarization Diversity Active Imaging illuminates a scene or target with a sequence of polarization states and then measures images of the polarization state scattered from a scene or target. These polarization images are then analyzed to provide additional details in the optical signature of objects by quantifying the object interaction with polarized light. The Mueller Matrix Imaging Polarimeter at The University of Alabama in Huntsville has been configured for bistatic scattering measurements of the Mueller matrices of small targets. The initial targets used were simple geometric shapes (spheres and cones). These targets were chosen because mathematical descriptions of their surfaces are easily obtained. Therefore, the measured polarization signatures can be compared with the known surface orientations. Data obtained indicated the ability of the PDAI technique to measure polarimetric signatures of the spheres and cones made of different materials (metals, plastics, and wood). In that data, there were evident relationships between various polarization properties and an object's material and shape. The results demonstrated the feasibility and the strong potential of the PDAI technique to determine the shape and orientation of an object from its polarization properties.

Book excerpt: This final report describes experiments into Polarization Diversity Active Imaging (PDAI) performed at the Physics Department of the University of Alabama in Huntsville (UAH). Polarization Diversity Active Imaging illuminates a scene or target with a sequence of polarization states and then measures images of the polarization state scattered from a scene or target. These polarization images are then analyzed to provide additional details in the optical signature of objects by quantifying the object interaction with polarized light. These polarization images are then analyzed in the following sequence: (1) Measure the Muller matrix image associated with the scene, (2) Map the retardance, diattenuation, and depolarization images for the scene, (3) Estimate the plane of incidence and target orientation pixel by pixel, and (4) Obtain estimates of the refractive index of objects in the scene and other information relating to texture. With a successful Polarization Diversity Active Imaging apparatus, a series of polarization images would be acquired, the image would be displayed, and then we could overlay images of the retardance, diattenuation, depolarization, orientation of the surface normal, and estimates of refractive index. These additional images would be useful for image interpretation tasks such as clutter rejection, target identification, target classification, target orientation, etc. Polarization Diversity Active Imaging may prove useful for many difficult imaging tasks such as satellite imaging, plume/hard body identification, hard body/wake, unresolved objects, and overcoming camouflage. But this present contract specifically aims to evaluate if Polarization Diversity Active Imaging could measure the orientation of bodies such as satellites in space and estimate their refractive index.

This book was released on 1998 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: A previous study presented interesting data indicating the ability of the Polarization Diversity Active Imaging techniques (PDAI) to measure polarization signatures of objects of simple shape (conical and spherical objects). Polarimetric signatures of such objects are obtained by applying a powerful decomposition technique, previously developed under earlier AFOSR contract. A complete description of the object in then obtained. Such decomposition can be used for detection, discrimination and classification of targets. This second phase has extended the study of the dynamic behavior of one of the previous targets (cone used as a re-entry vehicle mode.) By then rotating that sample target to make polarization movie, the evolution of the decomposed polarization signature can then the fully examined. The analysis performed for each position finally provides the dynamic behaviors of the target depending on either its orientation or the position of the detection system. The second goal of this phase was the development of a method for estimating the refractive index of a target from its Mueller matrix image. Our investigations show that the refractive index can be estimated either by using data resulting from the polar decomposition method or from the Mueller matrix image of the object after different steps of data processing. Such parameter is essential in order to progress in the understanding of these polarized high/material interactions.

Book excerpt: Polarized light is a pervasive influence in our world—and scientists and engineers in a variety of fields require the tools to understand, measure, and apply it to their advantage. Offering an in-depth examination of the subject and a description of its applications, Polarized Light, Third Edition serves as a comprehensive self-study tool complete with an extensive mathematical analysis of the Mueller matrix and coverage of Maxwell’s equations. Links Historical Developments to Current Applications and Future Innovations This book starts with a general description of light and continues with a complete exploration of polarized light, including how it is produced and its practical applications. The author incorporates basic topics, such as polarization by refraction and reflection, polarization elements, anisotropic materials, polarization formalisms (Mueller–Stokes and Jones) and associated mathematics, and polarimetry, or the science of polarization measurement. New to the Third Edition: A new introductory chapter Chapters on: polarized light in nature, and form birefringence A review of the history of polarized light, and a chapter on the interference laws of Fresnel and Arago—both completely re-written A new appendix on conventions used in polarized light New graphics, and black-and-white photos and color plates Divided into four parts, this book covers the fundamental concepts and theoretical framework of polarized light. Next, it thoroughly explores the science of polarimetry, followed by discussion of polarized light applications. The author concludes by discussing how our polarized light framework is applied to physics concepts, such as accelerating charges and quantum systems. Building on the solid foundation of the first two editions, this book reorganizes and updates existing material on fundamentals, theory, polarimetry, and applications. It adds new chapters, graphics, and color photos, as well as a new appendix on conventions used in polarized light. As a result, the author has re-established this book’s lofty status in the pantheon of literature on this important field.

Available in PDF, EPUB and Kindle. Book excerpt: Both an Expectation-Maximization algorithm and a lensless-APDI approach are presented for generating imagery directly from pupil-plane polarization measurements. Shortfalls of these methods and areas worthy of further consideration are identified. The use of pupil-plane polarization state measurements in place of pupil-plane intensity measurements in the APDI algorithm is explored. A framework for including polarization measurements into the APDI algorithm is demonstrated, and an initial statistical model and results are presented. Under the developed implementation, introduction of the polarization data doesn't result in better performance. Areas that may result in better reconstructions are discussed.

This book was released on 2009-01-01 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout much of machine vision’s early years the infrared imagery has suffered from return on investment despite its advantages over visual counterparts. Recently, the ?scal momentum has switched in favor of both manufacturers and practitioners of infrared technology as a result of today’s rising security and safety challenges and advances in thermographic sensors and their continuous drop in costs. This yielded a great impetus in achieving ever better performance in remote surveillance, object recognition, guidance, noncontact medical measurements, and more. The purpose of this book is to draw attention to recent successful efforts made on merging computer vision applications (nonmilitary only) and nonvisual imagery, as well as to ?ll in the need in the literature for an up-to-date convenient reference on machine vision and infrared technologies. Augmented Perception in Infrared provides a comprehensive review of recent deployment of infrared sensors in modern applications of computer vision, along with in-depth description of the world’s best machine vision algorithms and intel- gent analytics. Its topics encompass many disciplines of machine vision, including remote sensing, automatic target detection and recognition, background modeling and image segmentation, object tracking, face and facial expression recognition, - variant shape characterization, disparate sensors fusion, noncontact physiological measurements, night vision, and target classi?cation. Its application scope includes homeland security, public transportation, surveillance, medical, and military. Mo- over, this book emphasizes the merging of the aforementioned machine perception applications and nonvisual imaging in intensi?ed, near infrared, thermal infrared, laser, polarimetric, and hyperspectral bands.
