Abstract

A high-speed response photoelectric test device includes a transmitter (1) and a receiver (2), and three pairs of transmitting tubes and receiving tubes that can form three optical paths are embedded at the symmetrical ends of the transmitter (1) and the receiver (2). tube, the three pairs of optical paths are perpendicular to the symmetrical ends and have equal distances. The high-speed response photoelectric test device includes a transmitting circuit and a receiving circuit, which can convert optical signals into electrical signals and output TTL levels. The response time of the invention is less than 5us, and the separation speed test of the aerospace pyrotechnic separation device mainly based on explosive bolts can be realized, the operation is convenient, and the reliability and accuracy requirements of the test can be guaranteed.

Description

technical field

[0001] The invention relates to a high-speed response photoelectric testing device, which belongs to the application category of the photoelectric sensing technology field. Background technique

[0002] The photoelectric test device is based on the principle of photoelectric conversion. The transmitter and the receiver are installed in pairs to align the optical paths. When an object passes through, the optical path cutoff signal is converted into a level signal.

[0003] The aerospace pyrotechnic separation device, which is mainly based on explosive bolts, needs to perform a separation impulse test during the acceptance test to simulate the state of the bolt-like pyrotechnic product when it completes the specified function, and then determine its hazard to adjacent components. During the test, an optoelectronic test device is usually used to set the contact signal of the target point. By testing the flight time Ξ”t of the bolt head and the distance L of the t...
