Abstract:
The projection device includes an image-forming system and the illumination system. The illumination system includes a first light source device, a second light source device and a first light guiding device. The first light source device generates a visible light, while the second light source device directly generates a substantially pure infrared light. The light guiding device is adapted to guide the visible light and the infrared light to the image-forming system for processing to make the visible light form a visible light image and make the infrared light form an infrared light image.
