ABSTRACT:
A reflective scanning telescopic system comprises: a primary ellipsoidal mirror for collecting incoming light, a secondary hyperbolic mirror for reflecting the light collected by the primary mirror axially through the primary mirror, a tertiary ellipsoidal mirror, disposed behind the primary mirror for receiving the light from the secondary curved mirror, and a double bounce fold mirror for directing light reflected from the first fold mirror to the tertiary mirror and for reflecting light from the tertiary mirror past the first fold mirror to a light imaging system. Ideally, the telescopic system is mounted on a substantially rigid optical bench on a gimbal for supporting the optical bench and enabling the optical bench to scan in two dimensions by pivoting along roll and pitch axes.
