SYSTEM DESIGN OF INTEGRATED OPTICS SPECTRUM ANALYSER WITH TILTED FRESNEL LENS

摘要

Integrated optics spectrum analyser is the optical version of rf spectrum analyser with the capability of handling large amount of real time signal in a small , low power design. In this paper we determine the specifications and placement of the subsystems for a bandwidth of 400 MHz and resolution of 4 MHz at the centre frequency of 600 MHz. Computer simulation has been used to show that a tilted fourier transform fresnel lens has to be used to achieve low aberration over a wide band.
