英文摘要	the common camera lens usually includes the spherical glass/plastic lens and aspheric glass/plastic lens. however, spherical/aspheric shape measurement is still a key problem in the process of optical lens fabrication. at present, the in-process measurement of spherical/aspheric shape is conducted mainly by the probe-contacting method. but after a long time, its probe could be scratched severely and cause some big errors. laser shearing interferometry is a good substitute to some degree. nevertheless, it is not convenient for general shearing interferometer to carry out the in-process measurement because it is only suitable for certain kind of spherical/aspheric with respect to aperture or asperity. here a new lateral shearing interferometer is proposed to solve the described problems. it is based on two jarnin plates and rotatable prism pairs which are used not only for shearing displacement and direction, but also for fringe period and tilt degree, in order to meet requirements of various spherical/aspheric shapes or asperities. the new interferometer features a simple optical structure and two symmetric light paths, which makes its system with minimal error. the relation between shearing displacement, fringe period and prism angle of rotation is given in this paper. and the error source is primarily from the manufacture errors of prisms and plates. the final experiments show that one can achieve good-quality fringe patterns according to the requirement of measurement, concerning the shearing direction, shearing displacement, fringe period, tilt degree, etc. (c) 2014 elsevier gmbh. all rights reserved.
