Summary
Velocity interferometry is the technique of determining the velocity history of a specimen by illuminating it with a monochromatic light and optically detecting the small changes in frequency of the incident light caused by the specimen motion and carried in the reflected light. VISAR (Velocity Interferometry System for Any Reflector) was developed to measure the velocity of specimens with diffusely reflecting surfaces. The need for improvement led to the concept of a dual VISAR with an automatic data handling capability. The development of such a system is described here. The VISAR measures the velocity by collecting the data through an optical link and transfers representative electrical signals to the data handling system, where they are interpreted and displayed for analysis.
