Abstract
An optoelectronic apparatus includes an enclosure including a front face and a rear face. An array of emitters is contained in the enclosure and configured to generate first beams of optical radiation at a first wavelength and second beams of radiation at a second wavelength different from the first wavelength. Projection optics contained in the enclosure have an entrance face and an exit face and are configured to receive the beams of optical radiation through the entrance face and to project the beams through the exit face. A wavelength-based spatial multiplexer is contained in the enclosure and positioned to intercept the projected beams and configured to direct the first beams through the front face and the second beams through the rear face. A controller is coupled to selectively drive the array so as to control relative proportions of the optical radiation that are emitted through the front and rear faces.
