'''Velocity Interferometer System for Any Reflector ''' The Velocity Interferometer System for Any Reflector (VISAR) was developed by Barker and Hollenbach at Sandia National Laboratories in 1972. The technique works by using an interferometer to measure the minute Doppler shift in light frequency given to a laser beam as it is reflected from a moving specimen surface. The Doppler shift produces light fringes in the interferometer, and the number of fringes is proportional to the surface velocity.
