confocal microscopy

Scanned illumination with a fine pattern (e.g., diffraction-limited point) and detection through an aperture mask matching the illumination pattern in a conjugate field plane, which rejects out-of-focus light.

Confocal microscopy offers several advantages over conventional optical microscopy, including controllable depth of field, the elimination of image degrading out-of-focus information, and the ability to collect serial optical sections from thick specimens.
