LIQUID-CRYSTAL SELECTABLE BANDPASS FILTER

Abstract:

An optical device may include an optical filter array comprising an array of bandpass filters, and a liquid-crystal (LC) panel comprising an array of LC regions. An aspect ratio of the LC panel may match an aspect ratio of the optical filter array such that each LC region, of the array of LC regions, is associated with a respective bandpass filter of the array of bandpass filters A LC region, of the array of LC regions, may selectively transmit light that is incident on the LC region.
