The measurement and system error analysis of diopter and optical parallax in optical pointing system
The measurement of diopter and optical parallax of optical system is preceded traditionally with collimating device or diopter cylinder, the result of which is influenced largely by subjective operator. In order to increase the pointing accuracy of the telescope system, a high resolution CCD is adopted and the image of which is processed by computer, then the result of measurement is outputted by latter. The measuring method which is processed in the paper increase the degree of accuracy, cancel the influence of subjective factor and simplified the manipulation. Principle of test and measurement of diopter and optical parallax is represented and computation formula is deduced also. Then, error analysis of the test and measurement system is presented in the paper.
