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.
