Abstract
An optical sensing system can be integrated into a camera module. In particular, an optical element of an optical sensing system can be disposed entirely or partly within a barrel of a camera module. The optical element can be oriented toward a reflective surface, such as an infrared cut filter, such that an optical path is defined between free space and the optical element via at least one reflection off the reflective surface.
