An optical probe having simplified and optically improved means for obtaining movement of the field of view attitude and perspective. High light efficiency, optical resolution and depth of focus are provided, together with a substantial reduction in the number of optical and mechanical elements as compared to conventional visual flight simulation systems. A television camera has its field of view through a minor portion of the field of view of an extremely wide angle lens, and relative movement between the lens and the television camera provides a viewing attitude and perspective change without requiring tilting of the television camera or lens.
