Abstract
A statistical distribution model for point information in speckle photography is established using statistical approach. It is shown that the recognition of information is to recognize the space and direction of the Young's fringe from a random metrological field statistically. Based on the model, a 1-D recovnition technique is presented, in which the homomorphic filtering technique is used to elliminate both the speckle and the diffraction hole effects. Experiments show good accuracy and fast recognition speed.
