A method comprises illuminating a light receiving surface of a substrate comprising a three dimensional array of light receptors, where light receptors disposed in an x-y plane that is closer to the light receiving surface are responsive to light having shorter wavelengths than light receptors disposed in an x-y plane that is further from the light receiving surface, and where each light receptor is configured to output a binary value and to change state between an off-state and an on-state by the absorption of at least one photon and at the end of an exposure period, reading out binary values from light receptors disposed in at least two different x-y planes of the three dimensional array. |
