DIFFERENTIAL LASER DOPPLER METER for SPEED of missile element in the bore

摘要

Differential laser Doppler velocity of missile element notion in the barrel measuring device containing the laser, beam generator, beam splitter with a semitransparent mirror, a reflector and a light detector. To ensure determination of the instantaneous values ​​of the speed of missile element during its movement along the entire length of barrel channels with wide range of lengths of those, the optical contacts of photo-receiver with the surface of the missile element is provided indirectly through the reflector and the beamsplitter prism, which performs the function of the adder of reflected rays.
