Multi-thread laser power measuring device suitable for laser aging test

Abstract

The invention discloses a multi-thread laser power measuring device suitable for a laser aging test. The multi-thread laser power measuring device comprises an upper computer, a communication circuit, a photoelectric isolation circuit, a single-chip microcomputer and AD conversion circuit, a signal demodulation circuit, a program-controlled direct-current power supply, a laser power meter, a beam combiner, an optical modulator, a taper optical fiber, a high-low temperature box observation window, a collimating lens, an FC / PC connector and a test laser. Meanwhile, the program-controlled direct-current power supply sends the collected electrical parameters of each laser to the upper computer through the photoelectric isolation circuit and the communication circuit. According to the invention, output energy of laser can be effectively transmitted out of the high and low temperature box body through the collimating lens, the high and low temperature box window with a special process and the taper optical fiber, the test hardware can meet the requirement that the output power of a plurality of test lasers can be simultaneously acquired by software multithreading, and the optical pulse is arbitrarily set from 0.01 H to 10GHz; the direct-current power supply can be provided with three kinds of settings,: steady current, steady voltage and temperature power, the interfaces are abundant, the communication circuit supports an RS232 interface, an RS485 interface and a CAN bus interface, and the use is convenient and simple.

[0002] According to the requirements of military equipment automation and intelligence, a large number of optoelectronic equipment (as large as laser weapons, as small as single-soldier aiming range finder) is used in the military field, requiring the production units or departments of military optoelectronic preparations to produce military equipment with low cost and high efficiency. Photoelectric equipment and military equipment must first meet the environmental requirements. Mass-produced military equipment consumes a lot of manpower in the environmental testing process, which reduces production efficiency and increases production costs. The purpose of this invention is to use a laser power meter to Simultaneously monitor the output power of a dozen or dozens of lasers working under different environmental conditions, greatly reducing the time required for environmental testing, reducing the equipment cost of purchasing laser power meters and the labor cost of manual measurement. Therefore, the present invention designs a A multi-threaded laser power measurement device suitable for laser aging testing to solve the problems in the prior art
