摘要： Modulator devices are selectably adjustable between at least two states, wherein the transmission and/or reflection of particular wavelengths of light are modified. Certain modulator devices are substantially uniformly adjustable over a wide range of wavelengths, including visible and infrared wavelengths. Other modulator devices are adjustable over visible wavelengths without significantly affecting infrared wavelengths. In addition, the modulator devices may be used in conjunction with fixed thin film reflective structures.

摘要： Various methods are described to characterize interferometric modulators or similar devices. Measured voltages across interferometric modulators may be used to characterize transition voltages of the interferometric modulators. Measured currents may be analyzed by integration of measured current to provide an indication of a dynamic response of the interferometric modulator. Frequency analysis may be used to provide an indication of a hysteresis window of the interferometric modulator or mechanical properties of the interferometric modulator. Capacitance may be determined through signal correlation, and spread-spectrum analysis may be used to minimize the effect of noise or interference on measurements of various interferometric modulator parameters.

摘要： Embodiments of exemplary MEMS interferometric modulators are arranged at intersections of rows and columns of electrodes. In certain embodiments, the column electrode has a lower electrical resistance than the row electrode. A driving circuit applies a potential difference of a first polarity across electrodes during a first phase and then quickly transition to applying a bias voltage having a polarity opposite to the first polarity during a second phase. In certain embodiments, an absolute value of the difference between the voltages applied to the row electrode is less than an absolute value of the difference between the voltages applied to the column electrode during the first and second phases.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for detecting proximity and/or color of an object. In one aspect, an optical sensor includes a plurality of transmissive interferometric elements, a plurality of detectors positioned to detect the presence and/or intensity of light transmitted through the elements, and a processor to determine the proximity of an object based at least in part upon input from the detectors. An optical signal can be sensed by selectively actuating certain elements in a set of transmissive interferometric elements in an array to allow transmission of optical signals within a first spectrum through the array, and detecting optical signals transmitted through the array.
