Contemporary Approaches to Ensuring the Uniformity of Measurements of High-Speed Pulsed Electrical Processes

The laser rangefinder is a device that combines various technologies such as optoelectronics, electronics, microcontroller control technology, signal control, processing technology, and precision mechanical technology. This device has wide application value in aerospace, automatic control, industry, military, geodesy, and construction surveying, among other fields. The pulse laser rangefinder designed uses the SPLLL90_3 laser emitting diode for the laser emission circuit and employs the AD500_9 laser receiving diode for the laser reception circuit. The design of the laser emission circuit includes laser diode selection, emission, sample signal’s modulation circuit design, pulse signal generation, and driving circuit. The design of the laser reception circuit includes laser receiving diode selection, laser reception pulse signal’s acquisition circuit, reception signal adjustment circuit, and microcontroller peripheral circuit. After completing the hardware design of the pulse laser rangefinder, performance testing is conducted. The laser emission waveform and reception waveform are tested under an oscilloscope. The results show that the emission pulse generation and reception pulse acquisition circuits work normally. Range tests show that the rangefinder has a high degree of fit between theoretical and actual measurement distances within a certain time interval, meeting the design expectations. The designed optoelectronic rangefinder is adopted to evaluate the rationality of the design of building wall freeform surfaces through measurement. The results suggest that the designed optoelectronic rangefinder achieves higher detection efficiency and accuracy compared to traditional evaluation methods.
