Abstract
This disclosure provides systems, methods and apparatus relating to implementations of a switchable substrate that can be used in an imaging device. In one aspect, the switchable substrate includes a plurality of pixels, with each pixel having at least one switchable element. The switchable element can be switched between a first optical state and a second optical state. In the first optical state, a first spectral band of broadband light is reflected from the switchable element while a second spectral band is transmitted through the switchable element. In the second optical state, the first spectral band of the broadband light is transmitted through the switchable element while the second spectral band is reflected from the switchable element.
