Abstract
System and method for narrowing the transmission curves obtained using a spectral imager in which spectral images are acquired using a MEMS Fabri-Perot (FP) tunable filter. A method includes acquiring a first plurality of broad-band spectral images associated with respective MEMS FP etalon states and processing the first plurality of broad-band spectral images into a second plurality of narrow-band spectral images.
Claims76
A method for generating narrow-band spectral images, the method comprising:
- acquiring, by a spectral imager that comprises a tunable filter, a first plurality (N) of broad-band spectral images associated with respective states of the tunable filter;
- and
- processing, by a hardware processor, the first plurality of broad-band spectral images into a second plurality (M) of narrow-band spectral images.
A spectral imager that comprises a tunable filter and a sensor;
- wherein the sensor is configured to acquire a first plurality (N) of broad-band spectral images associated with respective states of the tunable filter;
- and
- a hardware processor that is configured to process the first plurality of broad-band spectral images into a second plurality (M) of narrow-band spectral images.
