Research output: Patent › Patent

Abstract

A light source device includes a first light source to provide a first input light beam in the direction of a central axis of the light source device, a second light source to provide a second input light beam in the direction of the central axis, a central reflector, a catadioptric reflector to focus light of the first input light beam to the central reflector, and to focus light of the second input light beam to the central reflector, and at least one actuator to change the angular position of the central reflector, so as to cause the central reflector to form an output beam by sequentially reflecting light of the first input light beam and light of the second input light beam to the axial direction.
