Abstract
An advance in a passive, remote sensing device for measurement of atmospheric temperature utilizes an actuated modulator for periodically alternating the radiation detected by a detector at a selected infrared wavelength between the infrared radiation from the atmosphere and that from the infrared reference radiation emitted from a reference material such that the detector compares the radiation emitted from the atmosphere to that emitted by the reference material at the selected infrared wavelength in order to determine the atmosphere temperature. Preferably, the modulator is a MEMS based modulator having a movable grating formed by MEMS based fabrication techniques.
