  • Fully articulated periscope camera system
    Patent number: 7936504
    Abstract: The camera or periscope system may include a taking lens, a beam steering device, a relay device, and an image rotation device. The camera or periscope system can be used to image in situations where the camera is not easily redirected to view a desired object of interest. The camera or periscope system is designed to be fixed to a mounting platform where the taking lens can be configured to point to the desired object of interest.
