1. A system comprising:
an infrared emitter to output infrared light towards a target, the infrared light reflecting from the target to produce reflected infrared light;
a detector to receive the reflected infrared light and to provide a signal based on the reflected infrared light; and
a lighting system comprising:
a light emitter to output visible light;
a mirror configured (i) to allow the visible light to pass through the mirror and to reflect the reflected infrared light onto the detector, or (ii) to allow the reflected infrared light to pass through the mirror and onto the detector and to reflect the visible light; and
one or more optical elements configured to affect the visible light and the reflected infrared light, the mirror being between the light emitter and the one or more optical elements or the mirror being between the detector and the one or more optical elements.
