Speed simulator for doppler laser speedometer. |
| 摘要 |
Frequency shift for a Doppler laser speedometer is simulated by retrodiffusion of the laser beam (26) from a rotating cylindroid (28), driven by motor (30), to simulate a constant speed target. Such device serves to test and calibrate a Doppler laser speedometer.
