摘要
提出了一个能够实时地监控拼接光栅状态的方案;理论上论证了氦氖光不能用来实时监控1740线衍射光栅的光栅拼接实验;提出了一种选择监控光波长的方法,使得拼接光栅的各种误差对于主光束和监控光的影响是一致的,并且通过实验进行了验证.
A detailed scheme by which the status of tiled gratings can be inspected in a real-time way is put forward. The He-Ne laser is shown to be inappropriate for the grating-tiling experiment where 1740/mm grating is used. A method is proposed by which the wavelength can be selected for the real-time measurement, so that the impact of all sorts of errors of the tiled gratings on the main beam（1053nm） and the beam for measurement is completely identical, which has been demonstrated by experiment.
