摘要：

A theoretical and experimental analysis is carried out of the fringe formation in speckle photography of the out-of-plane motion of a diffuse object. Multiple exposure technique has been used to sharpen the fringes. Intensity distribution at the fringe plane is investigated in case of filtering by collimated beam of light for double and multiple exposures. A good agreement is found between the theoretical and experimental results.
