Abstract

Laser detection systems possess advantages such as high ranging accuracy and strong anti-electromagnetic interference capability, but they are susceptible to interference from aerosols like smoke. To enhance the anti-smoke interference capability of laser detection systems, this paper theoretically analyzes the working principle of the Frequency-Modulated Continuous-Wave (FMCW) laser detection system, and by adopting this detection scheme, designs a miniaturized, low-power, and high-precision FMCW laser detection system prototype. An indoor test environment was established to conduct testing and verification of the prototype's ranging performance; the prototype's ranging function and error conform to the design requirements, laying a foundation for the practical application of the FMCW laser detection system.
