Wide field amplitude and phase confocal microscope with speckle illumination

This communication describes a wide field phase sensitive confocal optical microscope based on correlation between speckles. We show both experimentally and theoretically that the system operates as a wide field amplitude and phase confocal system; and demonstrate unique modes of operation such as extended focus phase measurement, which have, hitherto, only been demonstrated on scanning systems. Some potential applications of the system are discussed.
