ABSTRACT:
A system is shown which receives several radio frequency (RF) signals and applies these signals to a Bragg cell through which a beam of coherent light is passed and diffracted into several first order beamlets. The diffraction angle of the beamlets is a function of the frequency of the RF signals. The beamlets are amplified in an amplifier having a fast response time to match the response time of the system. Fiber optic bundles are provided at the input and output of the amplifier to guide the beamlets from a linear pattern into an areal pattern and to spread the beamlets for a more efficient use of the amplifier. The amplified beamlets are then formed into a linear pattern and applied to a photodetector to determine the frequency of the RF signals.
