  • Optical system alternating image capture and image projection
    Patent number: 7806533
    Abstract: An optical system comprises a first image capture device for capturing an image of an observation area, a first display device, a semi-reflecting plate, a concave mirror disposed facing the first display device, and a second display device for displaying a background image. A light beam is scattered by the first display device through the semi-reflecting plate and then reflected by the mirror and the semi-reflecting plate in order to display an aerial image between the semi-reflecting plate and the observation area. A projector projects a light beam toward one of the display devices. The first image capture device is adapted to capture the image of the observation area via said one display device. A alternating control device alternates capture of an image of the observation area by the first image capture device and projection of the light beam projected by the projector.
