An optical minimum configuration of a laser interferometer for noncooperative scattering objects is investigated. An optimization of the SNR (signal-to-noise ratio) of the homodyne receiver is achieved by beam design. Scattering measurement object surfaces generate a speckle pattern on the detector surface which influences the SNR. Within the whole operating range of the optics, the transmitted light spot on the surface under investigation should therefore be small. The receiving optics should image the light spot onto the detector surface. The detection of a noncooperative object in a distance of 26 m is proven experimentally.

Using the concept of matrix theory for lens design, a triplet lens can be replaced by a singlet lens which has an equivalent system matrix without changing its optical performance. Then, using third order Siedel's first aberration coefficient of the singlet lens is equal to zero, and the focal length and the physical length of the triplet lens are kept constant as constraints, an algebraic technique for optimizing a triplet lens is derived. Results show that this new optimizing technique is more effective than other conventional techniques for optimizing a triplet lens in the case of plane waves.

Based on scale diffraction theory, binary phase gratings are designed and the effect of fabrication errors on the diffraction efficiency and uniformity is discussed. The theoretical and numerical analysis shows that (0, non-(pi) ) grating is more sensitive to phase delay error than (0, (pi) ) grating. Patterning error is very complex to analyze, but we can give a maximum intensity deviation to the grating.

An all acousto-optic infrared scene projector (IRSP) has been developed for use in evaluating thermal-imaging guidance systems at the Kinetic Kill vehicle Hardware-in-the-Loop Simulator (KHILS) facility located at Elgin AFB, Florida. The IRSP is a laser source based projector incorporating Scophony illumination and scanning methods to produce 96 X 96 pixel multi-wavelength images at very high frame rates (400 Hz). The IRSP is composed of five functionally similar optical trains, four of which are fed with a different `color' infrared laser. The separate scenes from each optical train are then combined and projected simultaneously into the imaging guidance system.

The correction of phase aberrations in optical systems using an adaptive liquid crystal phase screen having 64 X 64 pixels is considered. These adaptive components have advantages over deformable mirror systems in that liquid crystal technology is relatively inexpensive and large pixelation densities can be achieved. In particular we address the application of these devices to astronomical adaptive optics. A simulator of the phase correction plate at work using time changing distorted wave fronts is described. Preliminary measurements of the optical flatness and response times of the prototype device are discussed.

Recent advances in axial gradient material fabrication via the diffusion of glass plates has opened the door to a wide variety of opticaldesign applications incorporating entire lenses of gradient index material. A proprietary software-driven process developed at LightPath Technologies Inc. creates gradient index glass by fusing together a stack of discrete glass plates, where each constituent plate has a distinctive composition and desired optical properties. LightPath's ability to prescribe large optical index changes (up to 0.47) throughout a glass substrate of virtually any diameter and thickness (macro gradient), invokes an interesting question: what are the properties of a solid gradient index lens and how can these properties be used most efficiently and effectively? This paper reports on a parametric study of third order spherical aberration vs. shape factor, for a macro gradient F/3 singlet lens whose index varies by ± 0.4 in linear, quadratic and cubic profiles.

Photon Dynamics' IPT system provides high throughput and excellent voltage measurement sensitivity on an AMLCD panel. It is based upon an electro-optical technology to measure the voltage stores on an LCD pixel of an AMLCD active plate. This paper discusses the system performance requirements. From these we derive the optical subsystem requirements. The opticaldesign form and its performance are presented. The current system status, system design issues, and the future improvements also are discussed.
