    • Disclosed is an illumination system using optical feedback to maintain a predetermined illumination output. The illumination system employs an electrically controllable optical filter for filtering light incident thereon. The illumination system also includes a light detector for detecting at least a portion of the light filtered by the electrically controllable optical filter. The light detector is in data communication with the electrically controllable optical filter. Some or all light filtered by the electrically controllable optical filter is detected by the light detector, which, in turn generates a corresponding signal that is compared to at least one predetermined value. If the signal generated by the light detector differs when compared to the at least one predetermined value, one or more filtering characteristics of electrically controllable optical filter are varied which, in turn, varies the amount of light filtered by the electrically controllable optical filter. The filtering characteristics of the electrically controllable optical filter continue to be varied until the signal generated by the light etector substantially matches the at least one predetermined value.
    • 公开了一种使用光学反馈维持预定照明输出的照明系统。 照明系统采用电可控滤光器来过滤入射到其上的光。 照明系统还包括用于检测由电可控滤光器滤波的光的至少一部分的光检测器。 光检测器与电可控光学滤波器进行数据通信。 由光可控光滤波器滤波的一些或全部光由光检测器检测,光检测器又产生与至少一个预定值进行比较的对应信号。 如果与至少一个预定值相比,由光检测器产生的信号不同,则电可控滤光器的一个或多个滤波特性被改变,这进而改变由电可控滤光器滤波的光量。 继续改变电可控光学滤波器的滤波特性,直到由光检测器产生的信号基本上与至少一个预定值相匹配。

    • An optical system and an imaging and display system using the optical system. The optical system has at least first and second optical elements aligned on a common axis. In one embodiment, each of the first and second optical elements can operate in an active state or in inactive state and comprise a photopolymer and liquid crystal combination. Each of the first and second optical elements is configured to transmit incident light substantially unaltered when each of the first and second optical elements operates in the inactive state. In the active state, however, each of the first and second optical elements does not transmit incident light substantially unaltered. Rather each of the first and second optical elements substantially alters light incident thereon when each of the first and second optical elements operates in the active state.
