| holographic | Of the nature of a holograph; pertaining to holographs. Source: Websters Dictionary (01 Mar 1998) |
| holographic microscopy | <technique> A mode of light microscopy in which a highly coherent, laser beam is split into a reference and main beam, with the reference beam (usually travelling outside of the microscope) being made to interfere with the main beam that has passed through the specimen. The interference of the two mutually coherent beams forms a hologram. The depth of field gained by viewing the hologram is essentially infinitely great, and the contrast mode or observation can be switched to dark field, phase contrast, interference contrast, etc., after the hologram has been formed by the microscope in bright field.

| holography | <physics> A technique for recording and later reconstructing the amplitude and phase distribution of a wave disturbance. (09 Oct 1997) |

| holography |
System of photography, using neither a camera not lens, in which laser beams create an interference patter recorded directly on appropriate light sensitive sheet film or plates. After processing, viewing the image by the light of a laser gives a three dimensional image.

| holography |
is the storage of the information of a light beam in an interference pattern. For recording, an image-bearing beam (=image or signal beam) is made to interfere with a second beam (reference beam) in the recording medium. Via a conventional photographic plate or the refractive index modulation in a photorefractive crystal, the interference pattern can be recorded. The recorded interference pattern is called a hologram. ...
