Abstract:
An imaging device may include (1) an aperture, (2) a lens positioned to direct light received through the aperture to a front side of an image sensor; and (3) the image sensor. The image sensor may include (1) a light capture layer including a photosensitive material that is dimensioned such that (a) a first portion of the light having less than a predetermined wavelength is captured by the light capture layer, producing a current, and (b) a second portion of the light having at least the predetermined wavelength passes through the light capture layer, (2) a conduction pathway that conducts the produced current to a current sink, and (3) an image sensor layer that includes at least one image sensor element positioned to receive the second portion of the light that passes through the light capture layer. Various other devices, systems, and methods are also disclosed.
