Abstract: An augmented reality projection device is provided. The augmented reality projection device includes an excitation light source that generates excitation light and a fluorescent light detector that detects fluorescent light generated in the fluorescent light generation area and generates a fluorescent image. The device also includes a projector that converts an image signal for displaying a visual indicator in the fluorescent light generation area into visual indicator light. The device further includes a processor that controls operations of the excitation light source, the fluorescent light detector, and the projection. The device further includes a coaxial optics that delivers the excitation light and the visual indicator light to the fluorescent light generation area and delivers the fluorescent light to the fluorescent light detector.

Abstract: In general aspect, a white excitation light generating device can include a fluorescent excitation light source that generates fluorescent excitation light, a first light source that generates first monochromatic light of a first wavelength different from a wavelength of the fluorescent excitation light, a second light source that generates second monochromatic light of a second wavelength different from the wavelength of the fluorescent excitation light and the first wavelength, a spectrophoto sensor that measures tristimulus values of at least one of the fluorescent excitation light, the first monochromatic light, and the second monochromatic light, and a controller that adjusts an output of at least one of the fluorescent excitation light source, the first light source, and the second light source on the basis of the measured tristimulus values.
