专利汇可以提供Sampling of deformation amount of object专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide a sampling of the deformation amount of an object featuring an excellent operability and adaptability on a simple electronic apparatus by displaying in real time the amount of deformation of a three-dimentional object in Moire fringe without unnecessary fringes.
CONSTITUTION: The reference grid (grid of straight lines and a fixed distance apart) is projected on an object 2 by a grid projector 1. The grid deformed by the object is picked up by a television camera 3, binary-coded in a binary-coding circuit 4, and put into a line-fining circuit 5 to obtain the central value of the deformed- grid width. The value is supplied to a primary interpolator 6 of m phases, and put into n frame memories 8 via switching circuits 7 (m circuits: S
0 S
m-1 ). The output of this and that of the primary interpolator 6 of m phases are put into AND circuits 9, and all of the m outputs is put into an OR circuit 10 to display on a television monitor 11. On the other hand, the output of a grid generator 12 is connected to the n frame memories 8 through the switching circuits 7.
