Paper Abstract

The results of a theoretical and simulated study of an infrared two dimensional time integrating spectrum analyser using a crystal of tellurium with infrared photorecievers time integration are presented. Spectrum analysis of the modulated input infrared laser radiation has been carried out with a very efficient single element two dimensional acoustooptic (2DAO) tellurium deflector. A simulated multifrequency spectrum analysis of radio signals has been performed. The frequency resolution can be scaled to cover a few hertz to tens of kilohertz. A minimum detectable input radio signal power at least two orders of magnitude higher, using Te as well as a wide banwidth can be obtained compared to other AO spectrum analysers which operate at lower wavelengths and utilize other materials than Te. Our previously reported experimental data is in good agreement with some of the simulated tests.
