Laser fuse enclosed feed testing device, testing system and testing method

Abstract

The invention discloses a laser fuse enclosed feed testing device, the testing device comprises a controller which receives initial time output by laser fuse and output an emission control signal through delay time delta T by taking the initial time as a reference; and a laser emitter, wherein an inlet circuit of the laser emitter is connected to the controller, and the laser emitter is used for receiving the emission control signal output by the controller and then emitting the laser to the laser fuse. The laser fuse enclosed feed testing device can obtain the delay time according to the laser fuse for detecting distance, and takes the initial time emitted by the laser fuse to generate the emission control signal; the laser emitter is controlled by the emission control signal to emit laser to the laser fuse, then a zone for a target can be discriminated according to the reception time and initial time of the laser, so that function examination of the laser fuse under laboratory environment can be realized.

Description

technical field [0001] The invention relates to a testing technology of a laser fuze, in particular to a closed-feed testing device, a testing system and a testing method of a laser fuze. Background technique [0002] For laser fuzes, test systems and test methods are important means to test products. Proximity detection of targets and timely detonation are the main functions of laser fuzes, and the anti-jamming algorithm that directly reflects the detection ability of laser fuzes and the anti-jamming ability of anti-jamming capabilities is the most important technical index of laser fuzes, and its value directly affects laser fuzes. The overall performance of the laser fuze, especially the large field of view laser fuze, has high requirements on the test site. Effective indoor static test methods and a fully functional closed-feed test system are important components of the laser fuze test system. [0003] The clock frequency of the existing laser fuze signal processing is...

AI Technical Summary

Problems solved by technology

[0005] Most of the traditional closed-feed test systems directly guide the emission window laser into the receiving window through optical fiber, and there is less intermediate optical signal processing process. The energy attenuation and signal delay can only be adjusted within a limited range, which is far from meeting the requirements of the entire clock cycle ( Several nanoseconds to tens of microseconds) signal delay adjustment and dynamic range (60dB) energy adjustment
