Abstract: A Micro-Electro-Mechanical System (MEMS) interferometer provides for self-calibration of mirror positioning of a moveable mirror. The moveable mirror is coupled to a MEMS actuator having a variable capacitance. The MEMS interferometer includes a capacitive sensing circuit for determining the capacitance of the MEMS actuator at two or more known positions of the moveable mirror and a calibration module for using the actuator capacitances at the known positions to compensate for any drift in the capacitive sensing circuit.

Abstract: Aspects relate to a handheld spectroscopy scanner including an optical window configured to receive a sample and a housing having the optical window thereon. The housing further includes therein a light source and a spectral sensor including a light modulator and a detector. The scanner housing further includes a processor configured to receive a spectrum of the sample from the spectral sensor based on interaction of light produced by the light source with the sample on the optical window. The processor is further configured to produce spectral data based on the sample spectrum for input to an artificial intelligence engine to produce a result based on the spectral data. In addition, the scanner housing may include a flange holding the light source and a heat sink configured to dissipate the internal heat generated. The housing further includes a cavity forming a handle for easy operation of the handheld spectroscopy scanner.

Abstract: A Micro-Electro-Mechanical System (MEMS) apparatus provides for self-calibration of mirror positioning of a moveable mirror of an interferometer. At least one mirror in the MEMS apparatus includes a non-planar surface. The moveable mirror is coupled to a MEMS actuator having a variable capacitance. The MEMS apparatus includes a capacitive sensing circuit for determining the capacitance of the MEMS actuator at multiple reference positions of the moveable mirror corresponding to a center burst and one or more secondary bursts of an interferogram produced by the interferometer based on the non-planar surface. A calibration module uses the actuator capacitances at the reference positions to compensate for any drift in the capacitive sensing circuit.
