    摘要： An embodiment of a double pass modulator includes a reflective polarizer adapted to pass light having a predetermined polarization state therethrough and to reflect substantially all other light, a quarter wave plate positioned to receive and pass light from the reflective polarizer, the quarter wave plate shifting the relative phase of the light passing therethrough by 45° with respect to the optic axis of the plate, and a reflector that receives light from the quarter wave plate and modulates at least a portion of the light incident thereon in a predetermined manner.

    摘要： A charge control circuit for controlling a micro-electromechanical system (MEMS) device having variable capacitor formed by first conductive plate and a second conductive plate separated by a variable gap distance. The charge control circuit comprises a switch circuit configured to receive a reference voltage having a selected voltage level and configured to respond to an enable signal having a duration at least as long as an electrical time constant constant of the MEMS device, but shorter than a mechanical time constant of the MEMS device, to apply the selected voltage level across the first and second plates for the duration to thereby cause a stored charge having a desired magnitude to accumulate on the variable capacitor, wherein the variable gap distance is a function of the magnitude of the stored charge.
