Abstract

Over the past few years, phased array antennas and variable RF/Microwave delay lines have been the subject of much research. This thesis presents a photonic solution to the generation of multiple, compact delay lines. Variable time delays are generated by optically tapping points on an acousto-optic cell by the use of a deformable mirror device. Isolation of a particular time delay is accomplished by the conversion of a time delay point into a corresponding spatial frequency by the use of appropriate optics. The desired time delay is recovered by heterodyning a local oscillator with the desired spatial frequency, selected by a tiltable mirror device. Multiple delay lines are produced by the use of a binary optic device. The design and simulation of the integrated optical system was carried out using a real ray tracing program written by the author. Theoretical signal to noise calculations are also carried out.
