亚特兰大激光公司为警方专门设计的人眼安全的激光二极管测距仪,通过发射一束很细的短脉冲红外光来测距,每秒钟可测量400次左右。测距仪利用高分辨计时器计测脉冲的来回时间,通过16位微控制器确定目标的相对速度。从头盔式显示器上,操作者可观察到射在目标上的激光束,并可读出显示的有关信息,但不影响前方观察。 Atlanta Laser’s specially designed eye-safe laser diode rangefinder for the police, which measures around 400 times per second by launching a very thin burst of infrared light. The range finder uses the high resolution timer to measure the pulse back and forth time, determines the target relative speed through 16 microcontrollers. From a helmet-mounted display, the operator can see the laser beam striking the target and can read the information displayed without affecting the front view.
