Abstract

This paper introduces a new advance about moiré interferometry of sticking film. That is, using a white light to replace the laser light and to illuminate the translucent grating that is set on specimen surface; we can get a high diffractive high frequency grating and a contrasty moiré fringe on the holograpthic film that adheres to the specimen.

In this method, the volume and cost of the equipment can be greatly reduced, experimental technique is very simple; this method can be used to dynamic measure too.
