木质材料表面对CO2激光的反射率研究

通过试验证实了木质材料表面对CO2激光反射的存在,根据基本光学理论建立木质材料表面对CO2激光的反射率数学模型.结果表明:木质材料表面对激光的反射率与激光偏振状态有关,对垂直于入射面的线偏振激光的反射率随着入射角的增大而增大,对平行于入射面的线偏振激光的反射率是随着入射角的增大先减小后增大.

Study on the reflectivity of ligneous material's surface to CO2 laser

The reflectivity of ligneous material's surface to CO2 laser is substantiated by experiment,then the mathematics model of the reflectivity is set up according to the basic principle of optics.The result shows that the reflectivity of ligneous material's surface to CO2 laser is related to the polarized state of laser;to the incident side-length linear polarized laser,the reflectivity increases with the angle of incidence increasing;to the linear polarized laser of parallel to the side of incidence,the reflectivity first reduces then increases with the angle of incidence increasing.
