    • Optical and mechanical apparatus and methods for improved virtual interface projection and detection, by combining this function with still or video imaging functions. The apparatus comprises optics for imaging multiple imaged fields onto a single electronic imaging sensor. One of these imaged fields can be an infra red data entry sensing functionality, and the other can be any one or more of still picture imaging, video imaging or close-up photography. The apparatus is sufficiently compact to be installable within a cellular telephone or personal digital assistant. Opto-mechanical arrangements are provided for capturing these different fields of view from different directions. Methods and apparatus are provided for efficient projection of image templates using diffractive optical elements. Methods and apparatus are provided for using diffractive optical elements to provide efficient scanning methods, in one or two dimensions.
