摘要
A new measurement method based on digital holography is proposed. The holographic registration of interferometric fringes generated on a surface under study using CCD camera and their reconstruction allow the determination of the surface shape with the aid of a computer program. Problems related to limited resolution of CCD camera devices are considered. The results obtained by numerical means are presented. The discussion on further possibilities is given.
