Abstract
A shearing generator comprising: an input light source; an image generator that generates two images of the input light source at an output plane, the image generator comprising a beam splitter that splits light from the input source into at least one pair of interfering light waves at an output thereof, and defines different optical paths for the light propagation of the light waves, said optical paths including at least one phase shifting element that provides for a different phase shift for the two paths.
