This paper describes an optical correlator for use in sonar ranging. The sonar system must process low probability of intercept signals while consuming minimum power. An optical correlator is favored because of the high efficiency of optical componen

The aberrations of Fresnel type grating lenses immersed in uniaxial waveguides are studied. Lens designs which account for birefringence and which are aplantic are presented.

The diffraction of aberration corrected Fresnel lenses in planar GaAs integrated optical waveguides are modeled on a desktop microcomputer. The simulated lenses are shown to be corrected for both spherical aberration and coma.
