Abstract
A video projector, a shutter mechanism for a video projector, and a method for providing a visible image and an infrared image. The shutter includes first regions that filter out visible light and second regions that filter out infrared light. The second regions are arranged between adjacent first regions. The shutter can be synchronized with an image modulator that alternately outputs visible light images and infrared images. The infrared images can be viewed using night vision goggles, allowing night vision goggle users to train in a simulated environment.
