Classification: CPC G | IPC G

Claim 0:
1. A system, comprising:
a tunable Fabry-Perot etalon, wherein the tunable Fabry-Perot etalon has a settable gap;
a detector, wherein the detector measures light intensity transmitted through the tunable Fabry-Perot etalon; and
a processor configured to determine a calibrated spectral measurement, wherein the calibrated spectral measurement is based at least in part on a measurement set of detected light intensities for a selected set of settable gaps and a reconstruction matrix, wherein the reconstruction matrix is based at least in part on calibration measurements using one or more field material targets illuminated, prior stored full calibrations for each of the one or more field material targets, and the selected set of settable gaps.
