Description
Technical Field

[0002] The principle of pulse laser rangefinder is to use the characteristics of laser beam to measure the distance between the target object and the rangefinder. Pulse laser rangefinder is usually composed of laser, transmitting module, receiver, clock, counter and data processing unit. During the transmission process, the laser beam generated by the laser is controlled by the recurrence control module and emitted. The laser pulse has high instantaneous power and short pulse width. It is usually an infrared laser. The emitted laser beam will pass through a certain lens or collimator to make it a beam as parallel as possible, and then shoot to the measurement target. During the receiving process, after the laser beam is shot at the target, part of the laser will be scattered or reflected back to the rangefinder by the target object. This part of the scattered laser is received by the receiving module and received by the receiver. The receiver will convert the received laser signal into an electrical signal, and then send the signal to the counter for counting through amplification and filtering. The counter calculates the distance between the measurement target and the rangefinder according to the number and time interval of the received light pulses, but there are still the following defects:
