A display system (44,56) includes an illumination (14) source configured to produce visible and nonvisible radiation and to direct the visible and nonvisible radiation along an optical path; and a modulator (16) disposed in the optical path configured to modulate the visible radiation to generate a visible image (47, 66), and to modulate the nonvisible radiation to generate a nonvisible data stream.
