  • Publication number: 20150138311
    Abstract: 360-degree panoramic camera systems include a plurality of modular cameras positioned at angular intervals to capture images around a 360-degree field of view, a camera-housing module configured to at least house the plurality of cameras, an electronic interface coupled to each camera, and an imaging system coupled to the electronic interface. The camera systems utilize technology that processes fixed images or raw video streams at a minimum of 24 frames per second. In so doing, these systems produce a high-resolution, seamless image of objects within the 360-degree field of view. The technology also allows for real-time correction of distortions, spherical projection, stitching, blending, white balance, etc.

  • Patent number: 8184375
    Abstract: A prism system is disclosed for splitting a broadband incoming light beam. In one embodiment, the broadband beam enters the prism system and is shifted laterally through a parallelogram shaped prism. The beam then encounters a first dichroic coating treated surface. The light that is reflected off of the surface strikes the internal wall of the prism to undergo total internal reflection within the prism. The beam exits the prism parallel to the original incoming broadband beam. The beam that passes through the dichroic surface reaches a second dichroic coating treated surface where a specified waveband of light is reflected while the remaining wavelengths pass through. The beam reflected by the second dichroic surface undergoes a total internal reflection and exits parallel to the incoming broadband beam. The light beam which passes through the second dichroic surface exits the prism parallel to the original incoming broadband beam.
