Conventional cameras have their natural antetype in the eyes of mammals providing "eagle eye" high resolution at the cost of rather bulky and therefore heavy optics. The single aperture objectives consist of several lenses required for generating an image of high fidelity. If extreme miniaturization and lightweight construction is required, Mother Nature goes for multi-aperture objectives known as facet eyes found in insects and spiders. These eyes consist of several adjacent imaging channels formed by individual micro-lenses and photo receptors responsible for imaging a part of the entire object field. facetvision's imaging systems are inspired by the multi-aperture compound eyes translated into artificial, technical systems based on CMOS and CCD imagers and microoptical lens arrays providing high resolution, extreme miniaturization and cost-effective production.
