Optimization of Spectroscope Parameters for Single-beam Pulsed Laser Scanning Circumferential Detection System

Aiming at the increasing demand for miniatureization of laser detector, a single-beam pulse laser scanning circumferential detection system is designed based on the principle of synchronous scanning circumferential pulse laser detector. The echo power equation of the optical system is established, and the optimal split ratio of the beam splitter is calculated. The lateral and longitudinal optical path dimensions of the device are analyzed, and the relationship between diameter and height is calculated. Combined with the optical lens design requirements, the volume of the system is calculated to obtain the relationship between volume and F-number, effective aperture and beam splitter radius. The study provides a reference for the miniaturization of pulsed laser scanning circumferential detector.
