Aperture correlation approach to confocal microscopy. Proceedings of SPIE 2984: 21-30 (1997).

We describe a new form of light-efficient real time confocal microscope which requires neither a laser nor scanning in order to obtain a real time confocal image. The approach is based on aperture correlation techniques.
