Abstract
According to one aspect, an IR spectrometer includes a light source adapted to illuminate a sample, a grating adapted to spectrally disperse a light that has illuminated the sample, a MEMS array adapted to be electrostatically actuated by a controller to control a diffraction of the light, a detector configured to detect the light, and a power source adapted to supply power to the light source and to the MEMS array, wherein the controller is adapted to control the MEMS array so as to manage a power consumption of the IR spectrometer. In one embodiment, the IR spectrometer includes a housing sized and arranged to house the light source, the grating, the MEMS array, the controller, the detector, to and the power source in a hand-held device.
