A digital simulation of frequency limitations and saturation effects in the power spectrum of a real time joint transform correlator (JTC) has been carried out. The results of optical image recognition using a real time JTC with a liquid crystal tele

The experimental conditions for the use of a TV camera with a digitizer board connected to a PC microcomputer as a densitometer is described. A general method is presented, based on different photometric tests, designed to ascertain the response of t

The process of comparing analogous images digitally obtained by means of a TV camera is studied. These images suffer degradation owing to defocusing, variation in the degree of coherence or because of later application of digital smoothing filters. A

A mathematical model describing the behavior of low-resolution Fresnel encoded lenses (LRFEL's) encoded in any low-resolution device (e.g., a spatial light modulator) has recently been developed. From this model, an LRFEL with a short focal length wa

When a large scale Fourier transform is required, the main disadvantage in the classical architecture for optical Fourier transforiing (froi front to back focal planes of a lens) is its length. If special detectors (CCD caDera), spatial sodulators (l

The polychromatic optical transfer function requires a considerable amount of time for measurement and calculation, which reduces the possibilities of its being applied to the evaluation of opto-photographic systems. As a simplification the authors h

A simple method is described for the automatic alignment and averaging of images by computer. The method is based on the use of the cross-correlation function of the projections of the images on two axes. The results presented are obtained from synth
