Abstract
A technique for generating an image having multiple hues includes filtering first photons at a first wavelength range using a first input filter section of an input filter, and filtering second photons at a second wavelength range using a second input filter section of the input filter. The first photons are directed towards a tube pixel set of a sensor, and the second photons are directed towards the tube pixel set. The first photons and the second photons are detected at the sensor. The first photons are received using a first output filter section of an output filter, and the second photons are received using a second output filter section of the output filter. An image is generated from the first photons and the second photons.
