| 摘 要： | 以光栅衍射方程为理论依据,对在入射角可变方式下,利用平面反射光栅进行激光波长测量的方法进行了研究.文中提出了一种测量方法,并给出了在该方法下利用光栅求激光波长的表达式,又结合该激光波长表达式,对影响激光波长测量准确性的误差因素进行了分析,最后还给出了利用该方法进行激光波长测量的实验结果.实验结果证明利用平面反射光栅,在入射角变化时,仍能比较准确地对激光波长进行测量.

| Abstract: | The method that measuring laser wavelength using grating under the condition of changing angle of incidence was brought forward basing on grating diffraction equation in this paper. The expression that calculating laser wavelength using this method was introduced, and errors that affecting measurement precision of this method was analyzed depending on the above expression also, moreover, the feasibility of this method was testified by measurement experiment. |
