摘要： A method and system for calibration of optical systems is disclosed. The system consists of a reference source (12), a spatial light modulator (26) for transmitting the reference source signal through non-imaging optics (30) and into the input of an optical system (36). The output of the optical system is then compared to the input signal and a correction is derived. The correction is stored and used real-time to adjust the output of the system to more accurately reflect the actual input signal.

摘要： A power conservative multi-segment LED transmitter including a multi-segment LED with a plurality of independently addressable LED segments, each LED segment suitable for selectively emitting a beam segment. A controller selectively enables and disables the LED segments. Depending on whether the beam segments overlap or not and whether low or high power is supplied to the enabled LED segments, the combined resulting beam may be a low power steered beam, a power conservative steered beam, an overlapping low power intense steered beam, or an overlapping power conservative steered beam. The steerable multi-segment LED transmitter and receiver system preferably includes an “all enabled” state in which each of the LED segments are enabled and emit a respective beam segment; a “training” state in which the LED segments are selectively enabled and disabled and the receiver determines substantially detected beam segments; and a “steered” state in which only the LED segments emitting the substantially detected beam segments are enabled.

摘要： A front light guide panel including a plurality of embedded surface features is provided. The front light panel is configured to deliver uniform illumination from an artificial light source disposed at one side of the font light panel to an array of display elements located behind the front light guide while allowing for the option of illumination from ambient lighting transmitted through the light guide panel. The surface embedded surface relief features create air pockets within the light guide panel. Light incident on the side surface of the light guide propagates though the light guide until it strikes an air/light material guide interface at one on the air pockets. The light is then turned by total internal reflection through a large angle such that it exits an output face disposed in front of the array of display elements.
