【Abstract】 The applications of holographic grating with low spacial frequency in the mesurements of tne focal length and the back focal length as well as the astigmatism of an optical system,the refractive index of a single lens,the curvature of radius of a convergent light beam and linear displacement are in- troduced and some of the experimentsal results are given in this paper.更多还原
