Abstract
A VISAR (velocity interferometer system for any reflector) with a new type delay leg is described, which uses multireflection in the étalon for increasing the delay time τ. When the incident angle is changed, the sensitivity of the VISAR can be changed. A few step values of the sensitivities can be selected for different applications. Experimental results for measuring the bullet’s motion in the 7.62-mm gun are presented.
