为了同时满足大视场、实时探测的要求,采用静态傅里叶变换干涉具,通过计算在-45°～45°范围内关于入射角度与相干条纹的光程差函数,仿真结果显示,倾斜入射干涉具会造成干涉条纹变密、暗带增宽、探测波长偏移等结果.提出了一种采用双干涉具循环运算的激光方向、波长的求解方法.采用折射率为1.46、斜楔角度1°的静态傅里叶变换干涉具做实验.由试验结果可知,每改变1°所对应的波长变化为2 nm,应用该方法可以在较大视场范围内求解激光方向及波长信息.

To obtain the big field of view and the real-time detectio'n request,the static Fourier transformation interferometer is applied to calculate the optical path difference function of incidence angle and interference position at-45°～+45°,and got the result that it deduces the interference pattern function of incidence angle.The paper develops a method of detection by double interferometers with 0.1°wedge and recursion algorithm for the integrative variable.There is an experiment of the interferometer with refractive index 1.46 and the wedge angle 1° for the feasibility of method,to collect the interference pattern and analysis,and the result of experiment proves that there are 2nm change when angle changed lo,so the method can get the spectral information in wide field of view,including the laser wavelengh and the angle of incidence laser from any direction.
