ABSTRACT:
An environmental protection system features a clear spinning curved volumetric enclosure to shed and throw off environmental contaminants such as rain, fog and dust that would affect a sensor image. The described design is especially suitable for cameras with extremely wide fields of view, such as panoramic or immersive cameras. Alternate forms of volumetric enclosures are described for different lens arrangements in compound camera systems. In all of these embodiments it is possible to keep the cover and the mechanism spinning it invisible to the cameras. An additional modification of the shape of the volumetric enclosure is described that prevents any accumulation of liquid drops within the fields of view of the sensors within the spinning volumetric enclosure. Alternate forms of construction with air and magnetic bearings are described for smoother and quieter operation of the spinning enclosure.
