ABSTRACT:
Light sensors in an imager having sloped features including, but not limited to, hemispherical, v-shaped, or other sloped shapes. Light sensors having such a sloped feature can redirect incident light that is not absorbed by one portion of the photosensor to another portion of the photosensor for absorption there.
