Proceedings PaperA New Approach to Acousto-Optic Spectrum Analysis

A consideration of the effects of the transducer upon the performance of Acousto-Optic spectrum analysers indicates that significant improvements to current systems can be made by the use of large transducer (high Q) cells in conjunction with novel system configurations. These considerations have lead to extensive work over the last couple of years at the Admiralty Research Establishment on polychromatic r.f. spectrum analysers.
