为研究适用于高温环境下微珠结构激光合作目标的反射性能,根据微珠结构激光合作目标的回归反射理论,设计和建立了用于测量微珠结构激光合作目标反射性能的实验系统。该系统使用激光波长为532 nm,激光发散角为1.2 mrad,最大输出功率为300 m W的半导体抽运全固态激光器作为激光发射装置,使用海洋公司的USB2000+型光纤光谱仪作为回波信号的接收装置。通过改变激光器的输出功率、测量距离等实验条件,对微珠结构激光合作目标和碳纤维板基底的反射性能进行了实验测量,并对所测量的实验结果进行了数据分析,为深入研究微珠结构的激光合作目标提供了测量方法和数据参考。
In order to study the reflection performance of laser target for microbead structure under high temperature environment, an experimental system for measuring the reflection performance of microbead laser target was designed and established according to the theory of regression reflection of microbead laser target. The system uses a semiconductor pumping all-solid-state laser with a laser wavelength of 532 nm, a laser divergence angle of 1.2 mrad and a maximum output power of 300 mW as a laser emitting device, and uses Oceanic’s USB2000 + optical fiber spectrometer as a receiving device of an echo signal . By changing the laser output power, measuring the distance and other experimental conditions, the microstructure of the bead laser target and the carbon fiber plate substrate reflection performance of the experimental measurement, and measured the experimental results were analyzed for further study of the micro-bead structure Laser Cooperation Objectives Provides Measurement Methods and Data References.
