NASA offers companies an optical system that provides a unique panoramic perspective with a single camera.
This technology emerged from NASA's advanced optics research for space applications. Unlike fish-eye lenses, which use refraction to produce a 190-degree image field, NASA Marshall Space Flight Center's panoramic reflecting optic lens uses both refraction and internal reflection to provide a unique annular (i.e., radial) 360-degree image field of view. The PRO lens can be shaped to view a small or large angular range of the entire region that surrounds the optical axis of the lens. The lenses production process involves simple lathing or injection molding of a glass or acrylic plastic. The simple manufacturing process enables low-cost production of MSFC's optical system. The ability of the system to acquire the 360-degree imaging information from a single vantage point is an important feature for many applications. For example, a PRO-equipped camera mounted on top of a vehicle could simultaneously view the entire surrounding area, providing optical information without blind spots. This image information could be archived so that dynamic incidents could be accurately reconstructed. In security systems, a single inexpensive camera could monitor, detect, and record movement around a large physical area, such as a parking lot or building grounds.
Patent Abstract: 
NASA's Marshall Space Flight Center has developed a technology that combines a panoramic refracting optic (PRO) lense with a unique detection system to acquire a true 360-degree field of view. Although current imaging systems can acquire panoramic images, they must use up to five cameras to obtain the full field of view. MSFCs technology obtains its panoramic images from one vantage point.
Benefits 

Full 360-degree field of view-this technology provides a radial image of the entire surrounding environment, from which any angle or image segment can be extracted and displayed horizontally.

applications 

In combination with a standard camera, this technology offers a visual radar system for transportation equipment, security systems, and monitoring devices. The unique 360-degree field of view can benefit a variety of applications:

Security/surveillance

Collision detection and safety alerts

Driver assistance

Monitoring and detection
