Lateral laser pulse synchronous detection apparatus

Abstract

The invention discloses a lateral laser pulse synchronous detection apparatus, which comprises a display control device, a conversion device socket and a photoelectric detector. The display control device includes a pulse counter and an outer display. The photoelectric detector is assembled at the bottom of a laser emitting channel of a to-be-detected pulse laser apparatus through a fixing support. When the to-be-detected pulse laser apparatus is working, laser pulses scattering from atmosphere are received, photoelectric conversion from the laser pulses from electric pluses is achieved, the pulse counter receives pulse signals sent by the photoelectric detector, counting and testing of time intervals for the laser pulses are conducted, and functions of testing the work cycle frequency, laser range finding frequency, repetition rate and the like of the to-be-detected pulse laser apparatus are achieved. The lateral laser pulse synchronous detection apparatus will not affect operation of the to-be-detected pulse laser apparatus, is small in size, low in cost and high in automation, is convenient to operate and use, and plays a certain assistive effect in improving the performance and managing the technical state of the service life of the to-be-detected pulse laser apparatus.

Description

technical field [0001] The invention belongs to the technical field of laser testing, and relates to a device capable of synchronously detecting and displaying laser pulses emitted by pulsed laser instruments. Background technique [0002] With the development of laser technology, pulsed laser instruments are rapidly used in various fields of national economy and national construction such as long-distance ranging and three-dimensional scanning. The most typical application is the laser rangefinder. When it is working, the internal laser emits a beam of laser pulses with a compressed beam divergence angle. The pulse is reflected by the target in the hospital. The receiving amplifier circuit receives and shapes. The logic counting circuit inside the laser range finder accurately measures the time interval between sending and returning of the laser pulse emitted by the laser range finder, and calculates the distance from the measured target. [0003] In practical application...

AI Technical Summary

Problems solved by technology

The disadvantage of this is to block the channel of the outgoing laser pulse to the target to be tested, which can only be tested in the test state, and cannot be tested in real time in the working state

At present, there is no instrument that can detect in real time whether the laser pulse emitted by the pulsed laser instrument is normal when it is working.
