Information About

Wavefront Coding




The technique was pioneered by a Radar engineer Edward Dowski and his thesis adviser Thomas Cathey at the University Of Colorado in America in the 1990s . After the university showed little interest in the research they have since founded a company to Commercialize the method called CDM-Optics . The company was acquired in 2005 by OmniVision Technologies , which has released Wavefront-Coding-based mobile camera chips as TrueFocus sensors.

Wavefront Coding falls under the broad category of Computational Photography as a technique to enhance the depth of field.
