Abstract

A high performance heterodyne interferometer is described that measures transient phenomena of flow fields. Data are acquired through 64 detectors in parallel with the output from each detector directed into a dedicated phase detector, digitizer, and buffer memory. This system operates at a 100 kHz frame rate with a precision of λ/300 rms.
