Physicist Dr Andy Harvey said it was a "simple system with a simple lens" which uses an optical encoder so that no information in images is lost. Developed primarily for military night vision cameras, the technology could find its way into camera phones. The quality of picture phone images is fast improving, with more models now capable of 1.3 mega pixel images."</i><br /><br /><img src="http://www.digitalmediathoughts.com/images/camera_wave203b.jpg" /><br /><br />The lens was developed as an optical encoder lens for thermal cameras. However, the uses are widespread. Using wavefront coding, the system encodes the image so it always looks the same without loosing any information. This technology should greatly help with cameras in mobile devices.
