Paper Abstract

This paper presents the concept and feasibility demonstration of an improvement of the LCD projector optics. An innovative concept of integration of an holographic filter in the optical head allows for laser pointer tracking. The filter retrieves the positioning information of the pointer on a PSD (Position Sensitive Device). The detector is interfaced with the LCD matrix in order to project a pattern on the screen. Several software options can be implemented for remote control of the slide show. We present the holographic geometry optimization, the experimental recording, and results.
