The theories of optical instrument are the Interdisciplinary of Optical Engineering and Instrument Science and Technology. The undergraduates should study the knowledge about the optics, precision machine and electronics. The courses such as Theory of Machine, Engineering Optics, even include some courses about Accuracy Analysis of Instrument are offered in the college. There are a lot of correlatives among these courses. This paper focuses on the structural logic of these courses. The order of these courses is researched, The aims of all the courses are clear completely to avoid the same topics to be taught twice in different courses. Therefore, the undergraduates would get the main line of the knowledge, and the professors would teach efficiently.
This paper described a kind of new method and system in dynamic measurement used to measure the diameter of cylinder. Laser prismatic technology, photoelectric sensor technology, fine machine technology, electronics data processing technology and computer figure control technology were used in this system. It was a system integrated with optics, machine and electronics. This system had some characteristics of high precision, high efficiency, real time, on-line, non-contact and automatic measurement.
The paper discusses a new kind of modern testing method used in magnification of telescopic optical system, which applied the technique of photoelectric imaging creation automatically based on DLP theory and the technique of collecting image based on CCD imaging theory. This method simplifies customary measuring process, realizes objective and automatic measuring, and avoids subjective error which artificial factor leads to with using customary testing method, so as to attaining higher testing precision.
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.
To measure the straightness and parallelism error of high precise and the overlong guides (or so 1500m) is different to measure the common guides. We apply principle of the optical collimation to measure the straightness error of the subsection guide in turn from the one end with laser collimation instrument. This way calls separate method. After measuring the straightness error of one of the datum guides, we measure the parallelism error of the guides. This way calls objective method. We can assess the straightness and parallelism error by adopting illustrate or numeration to compile procedure to deal with data and draw the curve of error.
