Zhao Li, Liu Yan, Xiong Jingwu. Down-dimensional Measurement of the Picture Flutter in the Film Projector by Linear CCD[J]. Editorial Office of Optics and Precision Engineering, 1989,(6): 44-48DOI:
This paper describes the principle of the dynamic down-dimensional measurement of small displacements and introduces a measuring method which adopts one chip linear CCD and uses a single chip microcomputer controller. The method is used for down-dimensional measurement of the picture flutter in the film projector.
