LASER DOPPLER DEVICE FOR MEASUREMENT OF VELOCITY OF MISSILE MOTION IN THE BARREL CHANNEL

摘要

A laser Doppler device for measurement of velocity of motion of a missile in barrel channel includes a source of electromagnetic oscillations and a device for reception and transformation of radiation. To increase accuracy and to provide determination of the velocity of the missile in barrel channels for broad range of calibers, a beam former is additionally used there, with beam-splitter prism with semi-transparent mirror and a reflector, and the source of electromagnetic oscillations generates coherent radiation in optical range of wavelengths.
