An automatic system for analyzing specklegrams point-by-point is described. A new method of evaluating Young's fringes is put forward based on making a TV camera to be able to scan horizontally and vertically. Tracking filtering and edge locating techniques are developed to acquire fringe data.?. Experiments show Young's fringes can be determined with the accuracy of 1% in spacing and 1 in orientation and accordingly the displacement can be found out with the accuracy of 1 it m in the range of 20 to 100 p m.
