Historically, the US Army, border security agencies as well as in transportation security planner has recognized the advantages of panoramic imagers, increased areas coverage with fewer cameras, tracking of multiple target simultaneously and others. However, panoramic imager has blind zone when using catadioptric system and required high bandwidth and heavy installation with fisheye lens to get an interesting resolution. The novel Panomorph lens is the heart of the new surveillance and security system developed by ImmerVision. The Panomorph lens is anticipated to be a new generation of lenses that can be used with NTSC or PAL camera to provide equivalent resolution than a 2 MPixels system but at a fraction of the cost by using existing facilities (cable, camera...). By introducing at the optical design stage a proper angular to pixel function (distortion), the new lens can provide a higher resolution in a define zone of interest than a standard fisheye. To achieve a gain in resolution, a pixel size well corrected image spot size is required. Our development included a strong optical design effort that resulted in an all refractive anamorphic panoramic imager with uncompromised image resolution for longer range detection in the zone of interest. The paper describes the development and real performance status of the Panomorph lens. Other components of the ImmerVision system include image correction, image compression and data transferred to handle devices. The same approach can also be used with IR imager where the number of pixel is limited.
