Abstract

See full text

A source assembly (48) configured to generate infrared electromagnetic radiation includes an emitter (60) that emits electromagnetic radiation over an emission solid angle. A portion of the emitted electromagnetic radiation is used in a detection. The portion of the user electromagnetic radiation surrounds the optical path in a usable solid angle. Electromagnetic radiation outside of the usable solid angle is focused back by a reflection assembly (64) onto the emitter to enhance the efficiency of the emitter.
