Abstract : Theoretical and experimental research is being conducted in the field of opto-electronic systems. The goal is to contribute solutions to problems of basic research importance which also have an underlying significance in practical applications that involve automatic pattern recognition and remote sensing. Excellent progress is reported on our study of image recognition in white light illumination. We on our study of image recognition in white light illumination. We are studying a new type of holographic frequency plane filter that operates over a broad spectrum in the visible. The concept of an achromatic Fourier transform system has also been reduced to practice in a variety of optical configurations. Secondly, a raytracing theory is being formulated for the analysis of sandwich-type holographic optical elements, and high quality elements are being fabricated. Related studies are reported on optical subtraction, optical metrology of fibers and machined surfaces, and the automatic assessment of image quality. (Author)
