✦ Synopsis
We have experimentally demonstrated vibration analysis of a re ecting object in time-average mode using shearing interferometry and interferometric grating. Experimental results show that time-average moirà e fringes, formed between fringe pattern re ected from object and sinusoidal grating are modulated spatially by the amplitude of vibrating tilt. From the experimental results, information regarding tilt of vibrating objects can be determined.
