Tunable moiré grating for optical mapping
Optics Letters, 1979The use of a moiré pattern as a tunable grating is proposed. The moiré pattern is created by placing one grating upon another with a varying angle between them. A demonstration of the use of this tunable grating for moiré mapping and a discussion of the limitations and possible applications of this method are given.

Optical Mapping of Arrhythmias
2000Optical mapping of voltage dependent fluorescence in cardiac tissue allows for the simultaneous measurement of membrane potential from many locations on the surface of the heart. The development of this technology has revolutionized the field of cardiac electrophysiology and has provided new insights into the mechanisms of initiation and maintenance of

Abstract An optical technique for performing general types of map transformations is introduced. Using a coherent system, the object distribution is multiplied by a phase function so that its frequency spectrum constitutes the transformation wanted. Also shown is how imaging systems can be made space variant.

Whole-genome shotgun optical mapping is one of the new genome-scale technologies that is dramatically changing our approaches towards understanding bacterial genome structure. Optical mapping quickly provides a picture of the number of chromosomes and extrachromosomal elements in a bacterium, without the uncertainties of data obtained by the ...

SPIE Proceedings, 1988
Holography can be used for arbitrary, parallel, weighted mappings between planes with up to to 106 pixels each at I/O limited rates. This allows precalculated mappings to occur at very high speed. The applicarttions for one-to-one, one-to-many, many-to-one, and many-to-many maps are explored here.

Abstract : This report describes the support services provided by Keo Consultants to the operation and improvement of the All Sky Imaging Photometer on the NKC135 Airborne Ionospheric Observatory. It describes two new intensified camera systems constructed for the ground-based support of the airborne measurements and gives examples of the data obtained.
