Abstract: A system for determining a calibrated spectral measurement includes a tunable Fabry-Perot etalon, a detector, and a processor. The tunable Fabry-Perot etalon has a settable gap. The detector measures light intensity transmitted through the tunable Fabry-Perot etalon. The processor is configured to determine the calibrated spectral measurement. The calibrated spectral measurement is based at least in part on a measurement set of detected light intensities for a plurality of settable gaps and a reconstruction matrix. The reconstruction matrix is based at least in part on calibration measurements using multiple source wavelengths and multiple settable gaps.

Abstract: A system for determining a spectrum includes an interface and a processor. The interface is configured to receive a sample set of intensity data for an array of spatial locations and a set of spectral configurations. The processor is configured to determine a region of interest using the sample set of intensity data and determine a spectral peak for the region of interest.

The detector measures light intensity. The processor is configured to determine the calibrated spectral measurement. The calibrated spectral measurement is based at least in part on a measurement set of detected light intensities for a plurality of settable gaps and a reconstruction matrix. The reconstruction matrix is based at least in part on calibration measurements. For a calibration measurement, a settable gap is selected and a set of input monochromatic source wavelengths is used to measure responses at a detector after transmission through the Fabry-Perot etalon. Each input monochromatic source wavelength is also measured using a radiometer to scale detector measurements.

Abstract: A system for machine vision spectral imaging includes a spectral imager, a substrate, and a processor. The spectral imager comprises a Fabry-Perot etalon including a settable gap. The substrate has relative motion with respect to the spectral imager. The processor is configured to identify an object in a set of images from the spectral imager, wherein each of the set of images is associated with a specific gap of a full set of gaps, wherein the full set of gaps comprises a set of gaps setting the settable gap covering a complete range of the settable gap needed for a full spectral image of the object.
