Abstract

We have demonstrated operation of a tellurium dioxide non-collinear acousto-optic filter which has been placed under the programmable control of a SYM 1 microcomputer. One program provides for automatic scanning through the spectral range (450 to 750 nm), stopping at each line above a specified threshold for a scale expanded scan; the center frequency, bandwidth and relative intensity of each line is displayed. We can also program the RF power level to be normalized to the detector and filter response functions. A programmable stored replica can be used to compare the measured spectrum with specified characteristics of a spectrum stored in the computer, so that various comparison operations can be carried out. One of the advantages of the AO filter is its easy adaptability to computer interfacing while sacrificing none of its speed of operation, and these qualities have been incorporated in this demonstration.
