Abstract

An optical projection system includes an image forming system such as projector including an image source and an image relay adapter. The image source includes an array of image pixels. The image relay adapter includes a body having an inlet operatively connected with the image source and an outlet separated by a predetermined distance from the inlet. The image relay adapter also includes an image relay system in the body which receives the image from the image forming system and relays a replica image to the outlet. A hemispherical projection system can be operatively connected with the outlet of the image relay which projects the array of image pixels from the image relay adapter onto a truncated spherical surface at a projection angle of at least 160 degrees. Further, the hemispherical optical projection system can project the array of image pixels into a hemispherical projection having constant angular separation among adjacent image pixels, such that the projection is suitable for projection onto truncated spherical surfaces of varying radii without requiring spatial distortion correction of said array of image pixels. An acquisition device can also be utilized with the image relay adapter of the optical projection system to acquire images suitable for hemispherical projection at an angle of projection of at least 160 degrees without spatial distortion. Methods of hemispherical optical projection are also provided.
