The paper discusses a modern method to test the out pupil diameter and out pupil distance of the optical system. It is based on DLP technique of optoelectric graph generating automatically, CCD imaging technique and l image processing technique of computer. This method takes advantages of fast testing, high precision, high automatization and numeralization.
This paper discusses that we apply the projection technique of DLP to the target generator of optics. So we carry out the imaging creation automatically. And we will apply this technique to the modern test of optics system parameter. If CCD is receiver, it can achieve auto-measuring. Thus, this testing system is more objective, exacter, better measuring efficiency, and it can replace the traditional measuring method by eyes gradually.
