本文以和差基线匹配干涉仪测角为例,介绍了干涉仪测角中多余信息的获取方法,提出利用多余信息改善测角精度的设想,导出了精度改善关系式。
In this paper, taking the measurement angle of the sum and difference baseline matching interferometer as an example, the method to obtain the extra information in the interferometer angle measurement is introduced. The idea of using the extra information to improve the measurement accuracy is presented.
