摘要
针对脉冲激光应答测距易产生传输延迟时间抖动进而影响测距精度的问题,选用LD激光器,采取自动温度控制、自动功率控制和高精度的脉冲时刻检测等技术,研制了极小时延抖动脉冲激光应答机.光源试验结果表明,该设计的时延抖动<1 ns,有效提高了测距精度.
Aiming at the problem of the translate time delay＇ s jitter with pulse laser ranging, further the jitter affects the accuracy of the ranging. The minimal time＇ s delay pulse laser responder were designed adopting some techniques such as the diode laser, automatic temperature control, automatic power control and the detection method of the high-accuracy pulse time. The results of light experiment indicated the pulse of jitter less then 1 ns, the accuracy of ranging was effectively improved.
