Paper Abstract

An acousto-optic filter was developed utilizing two Bragg-Cells, an integrating photo-detector array and a high frequency, non-integrating Avalanche Photo-Detector (APD). The basic architecture is that of a Mach-Zehnder interferometer. This device simultaneously provides two output signals, 1) The power energy spectrum of all signals S(t) within the one octave bandpass of the device, and 2) a down converted IF signal containing the real phase and amplitude information of any desired individual signal, S1(t), or S2(t), or S3(t), etc, etc, within S(t).
