Frequency-offset, solid-state laser coherent Doppler velocity measurements of high-speed targets.
Diode-pumped, single-frequency Nd:YAG lasers were used to measure velocities of laser-accelerated targets over a range of 0.1 to greater than 2 km/sec. A 1-GHz optical heterodyne receiver was used with a tunable, frequencyoffset local oscillator to compensate for Doppler shifts of as much as 4 GHz.
