摘要：
A laser velocity calibrator for a nuclear gamma-resonance (NGR) spectrometer is described. The calibrator operates on ″beats″ generated in the interference of the primary beam of an LG-52-3 gas laser and the beam reflected from a moving mirror. The amplifier-shaper system for converting the sinusoidal ″beat″ signal into pulses of standard shape is built on integrated microcircuits. The operation of the calibrator is tested by measurements of the spectrum of metallic iron. The calibrator being described was used to measure velocities in the range of 0 to plus or minus 30 mm/sec.
