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 reflective properties of the beads structure laser cooperation targets which are applied in the high temperature, according to the regression reflection theory of beads structure laser cooperation target, an experimental system is designed and built for measuring the reflective properties of the beads structure laser cooperation target. The laser emitting device of the experimental system is a diode-pumped solid-state laser. Its wavelength is 532 rim, the divergence angle of the laser is 1.2 mrad, and the maximum output power of the laser can achieve 300 roW. A fiber optic spectrometer produced in the Ocean Optics with the model number of USB2000＋is used as the receiving device. Through changing the laser output power or measuring distance, the reflection properties of the beads laser cooperation targets and carbon fiber base are measured. The measured data are analyzed, which provides a measurement methods and reference for further study.
