Digital holographic movie by using a point diffraction interferometer
A method to obtain a digital holographic movie by means of a point diffraction interferometer is described. By using a parallel aligned liquid crystal wave plate of size 3 × 3 cm2, a phase shifting interferometric technique is implemented. The optical setup is able to operate at 10 framess. Each fra...
