| Abstract: | The oscillating mirror is the most important one of the subsystems for the multispec-tral scanners. The requirement of moving linearity for it is very critical. The principle and methods of the test using high speed photography for the oscillating mirror are discussedin this paper.Both direct and indirect photographic testing methods are presented. And how to determine the photographic parameters to meet the requirements of measuring accuracy are also given.It can be seen that high speed photographic method is more efficient than others for this measuring purpose. |
