High-resolution TeO2 acousto-optical deflector for millimeter-wave spectrometer
Abstract
This paper introduces high resolution TeO2 deflector for mm-wave radio spectrometer. We have developed mm-wave acousto-optic radio spectrometer using these devices; it has 17.5 KHz frequency resolution, 13 MHz bandwidth and the system drift is +/- 0.03 channel per hour.
