A ring array camera includes a telescope for focusing an image onto an imaginary focal plane, an annular array of image detecting elements disposed on a substantially flat disc, a primary reflector cone positioned proximate the imaginary focal plane and having a substantially conical primary reflecting surface reflecting the focused image radially outwardly, and a secondary reflector positioned radially outwardly of the primary reflector and having a substantially conical secondary reflecting surface reflecting the focused image from the primary reflector cone onto the annular array of image detecting elements. In a second embodiment of the invention, a linear actuator is connected to the primary reflector cone for reciprocating the primary reflector cone to scan the focused image radially inwardly and outwardly across the annular array of image detecting elements.
