Abstract

This paper presents an acousto-optical analog microwave spectrometer (AOS) with a serial-type acousto-optical unevenness (AO) interaction of less than 3 dB in the frequency range 500 MHz to 1750 MHz central frequency. As an acousto-optic modulator AO processor is used with the effective generation of bulk acoustic modes with the surface of the lithium niobate crystal YZ- cut by an optimally apodized interdigital transducer (IDT), calculated with the diffraction divergence.
