摘　　要：迈克尔逊风场探测干涉仪视场展宽的实现在于臂玻璃材料的选择和厚度的确定。依据视场展宽的4个条件,经过分析计算,从中国玻璃库中选出了最佳玻璃对LAF4和ZF2,并计算出了臂厚度值。经过验证,此选择很好地满足了视场展宽条件。将相关参数输入计算机,通过模拟干涉仪的结构并进行光线追迹,得到了视场展宽干涉图。经过数据反演得到了风速值41.48 m/s,与理论值47.62 m/s基本一致。The field widening of a Michelson interferometer for wind measurement is determined by the material and thickness of arms.On the basis of the principle of field widening,two kinds of qualified glass LAF4 and ZF2 were selected in Chinese glass database and the thicknesses of the arms were calculated.The results validate the effectiveness of the two kinds of glass in field widening.Finally,the related data were applied to a computer to simulate the interferometer configuration and to obtain the interferogram ...
