摘要: A beam alignment system having a source for producing first of electromagnetic radiation considered an or reference beam, second to be aligned with the and pair rotating mirrors capable being optically interposed at different times across optical path beams. The axes rotation are transverse each other in order enable mirror provide information about beams respect two planes. is indicative time difference between reception by detector reflected from mirror. These differences utilized signals which used adjust position bring into
