Available in PDF, EPUB and Kindle. Book excerpt: Modern radar, telecommunication, sonar, and radio-astronomy systems use integrated systems, complex signals, and signal processing methods exten sively. These systems require the development of new, more efficient systems. One of the major ways to improve radar and sonar systems is to use multichannel systems, the most promising of which employ space-time signal processing. In the last few years the intensive growth in electronics, informa tion processing techniques, microwave and laser technology, electrooptics and holography, acoustics, and optoelectronics have resulted in new scientific and technological research fronts. One of these is the theory and technology of electrooptical array antennas-a new class of receiving antennas whose pat tern is controlled by means of coherent optics and holography. Electrooptical array theory and technology have been involved in the study of the power, resolution, and range characteristics of arrays with various coherent opti cal processors. The practical applications of these systems and methods for building them using contemporary optoelectronics have also been studied.

Download or read book The Theory and Physical Constraints of an Electro-optical Signal Processor for Phased Array Antennas written by L. Lambert and published by . This book was released on 1963 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques are described for processing the signals obtained from the elements of a phased array antenna by means of electro-optical devices. These techniques employ one electro-optical device which simultaneously forms, as a continuum, all the beam patterns that a receiving planar array antenna is capable of forming. An analysis of an electro-optical processor for phased arrays is presented which shows that: (1) the target location angles are obtained unambiguously for each and every target that can be resolved; (2) target angle resolution is identical to the resolution inherent in the antenna array; (3) multiple targets produce multiple outputs with all angles properly associated; and (4) the progressive envelope delay that is introduced at the antenna array does not result in an aperturebandwidth constraint. Physical constraints on system bandwidth and the number of array elements that can be processed are considered. Typically, it should be possible to process electro-optically 10,000 array elements with a system bandwidth of 10 Mcs. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: It is no wonder that research in Si photonics (optical components embedded on a silicon platform) has bloomed so rapidly the last few years. Combining low loss, strong refractive index contrast (and, thus, light confinement), with electro-optical and thermo-optical effects, allows for the fabrication of dense and complex electro-optical Si photonics systems. Moreover, because it is based on the well-established platforms of the CMOS industry, Si photonics is expected to rapidly shift from a research field to the production of high volume, low cost, complex, integrated electro-optical systems. One class of systems receiving increasing interest are Nanophotonic Phased Arrays (NPAs), which offer free space emission of a manipulated beam that can be steered, focused, have controlled angular momentum and even create holograms. Still, some substantial challenges remain in applying these NPAs to real systems. Large cell size and spacing between adjacent antennas produce multiple beams and reduce effective steering angle. In addition, small beam angle requirements and large aperture in NPAs receivers demand large phased array size. In order to allow for both steering angle and large aperture, a large array with small cell size is required resulting large number of unit cells in one array. In this work, we first propose two metallic nanoantennas to couple between a waveguide mode to free space radiation. Then, by combining existing Si photonic components like directional couplers and modulators with optical antennas and phase shifters that were designed for this goal we demonstrate, in this work, several NPAs for various applications. Using unique architecture, we then, specifically focus on a, NPA based, lidar. These lidar systems are essential components in any autonomous system maneuvering in an undefined environment. An on chip lidar like this one can serve, for example, in the automotive industry for safety enhancement and to allow autonomous driving functionality at an affordable price.

Available in PDF, EPUB and Kindle. Book excerpt: In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.

Download or read book Microlens Arrays written by Dan Daly and published by CRC Press. This book was released on 2000-11-23 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general trend towards miniaturisation and parallelism in optics and electro-optics has led to a requirement for arrays of sub-millimetre sized lenses. Thus, the demand for these microlens arrays has increased dramatically over recent years. Dan Daly's book describes the technology of microlens arrays and provides a recipe for producing them. It surveys the many fabrication techniques and discusses the numerous applications which either require or enhanced by the use of microlens arrays. This book gives a full description of the processes involved in production and limitations of the techniques. Processes looked at include the Thermal Reflow of Photoresist technique and the Silicon Elastomer Replication Process. As the measurement of microlenses is an intrinsic part of the production process, the methods which can be used to evaluate lens performance are explained.
