The development of the Dual Detector Velocity Inter­ferometer System for Any Reflector (VI SAR) provides an effective instrumentation tool for measurement of specimens moving at high velocities without adding mass or causing extraneous resonances that are commonly encountered in the instrumentation process. The development of this instrument is the logical extension of the basic Velocity Interferometry System developed in 1972. The extension consists of introducing a dual detector system to eliminate ambiguous data, adding digitizers to record data, and adding a data reduction system to interpret the recorded data and recover a time velocity history of the specimen action. In the process of developing the data analysis theory, a new "array" mathematical procedure is used to analyze the wave­forms as vectors rather than a series of discrete measure­ments. This analysis procedure both simplifies the reduction process in theory and in the steps required to accomp­lish reduction.
