Abstract

A new optical head for an electronic speckle pattern interferometer (ESPI) has been designed. The special design is that of a diffuser and a mirror instead of all optical elements and mechanisms of the existing optical head. Another special design is that of a double frequency grating adopted as a shearing element. The new optical head can be operated as a double beam speckle interferometry and shearography. It is light in weight and has very good anti- disturbance function. The experiments are successful when they are combined with an image processing card and software.
