Burst correlation processing in LDV
Abstract
The paper describes a 10-ns burst correlator for LDV signal processing which consists of a 10-ns photon correlator and a 50-microsec Fourier processor. The device incorporates five major changes relative to previous photon correlation LDV equipment: (1) ECL 10-ns circuitry, (2) custom LSI store, (3) 50-microsec Fourier output processor, (4) microprocessor control of all facilities, and (5) new 'combined optics' package for fringe and two-spot operation. The new instrument gives real-time velocity tracking up to 10 kHz with the highest accuracy and sensitivity.
