Abstract
We discuss the resolution limits of digital TV holography used for nondestructive testing. A phase shifting technique converts the interferometric information into a phase distribution image. Spatial low pass filtering improves the phase accuracy at the expense of spatial resolution. Experiments show that spatial details down to 2.5 × 2.5 pixels and displacement below λ/100 may be resolved.
