Abstract: A method for operating a lamp is disclosed having the steps of providing an electric lamp having a pair of electrodes and an arc gap therebetween, providing a power supply for applying a voltage and current to the electric lamp, and providing a controller having means for sensing parameters and configured to control a signal to be applied by the power supply to the electric lamp. The method further includes sensing the parameters of lamp operation. The sensed parameters are compared with desired lamp parameters. The controller commands the power supply to add a current pulse to a specific portion of the pulse.

Abstract: A solid state multi-spectral light source for a multi-spectral light source (10) system includes an array of LED groups, wherein each LED group (12) may include red, green, and blue LEDs. The LEDs produce color light bars by activating the appropriate color LEDs. The color light bars can be flashed or scrolled to integrate a color display.

Abstract: A prism is mounted onto a motor without regard to its rotation angle relative to the motor index. Its position is electronically set later after construction of the optical path. A motor controller is used to control the rotation of the prism. This motor controller keeps the prism spinning at a constant velocity and positions the prism phase (rotation angle versus time). A variable offset is used to position the absolute prism rotation as a function of time. The phase may be advanced or delayed by an operator during set up. Each prism has its own phase. The phase of each prism in the system is set so that the illumination pattern correctly matches the video addressing of the panel. This is a one time set up during construction. The correct positions are set, and stored in non-volatile memory for life.

Abstract: A method of reducing the artifact in color sequential LCD projection systems while providing flicker free and stable lamp operation. The method consists of establishing the frequency of lamp pulsing at a rate in response to the display frame rate. A further refinement is achieved by alternating a sequence of intervals of enhanced brightness with a sequence of low lamp current levels in successive frames to minimize spatial modulation.

Abstract: A head-mounted projection display system is characterized by a pair of head-mounted low-power image projectors mounted adjacent the eyes of the viewer, and aimed to project in a direction along the line of sight of the viewer toward a high-gain, retro-reflective screen (16). Stereoscopic viewing is enabled by projecting separate images to the right and left projectors. The retro-reflectivity of the screen (16) ensures that the right and left images will be returned to the right and left eye, respectively.
