It is possible to obtain detailed form deviation of whole flank of objective gear tooth by laser interferometry using large angle of incidence. But it takes much time to process data of brightness intensity on CCD image sensor, and the method is not introduced in production line for the sake of optical instability of the measuring system. Therefore to detect a tooth form deviation of a cylindrical involute gear, a new measuring system is considered. The effectiveness of this method of rapidly detecting a tooth form by using laser holography is investigated.
