Abstract

We have used a computer-generated holographic optical element (HOE) with electronic speckle pattern interferometry to calculate the interference phase corresponding to the deformation of a test object from a single TV frame. The HOE is a modified crossed phase grating that introduces a known phase change between the ±1 diffracted orders, without being translated. The progressive propagation of transient mechanical waves was measured with an rms precision of 2π/30.
