Abstract

Future airborne surveillance systems require high performance optics to provide high spatial resolution over wide field of view. The system for 10 km altitude needs to resolve a ground target of 10 cm over 6 degree FOV. The spectral range covers from 0.4 to 10.0 micrometer. The spectral bands of interest include the visible, near infrared, MWIR (middle wavelength infrared), and LWIR (long wavelength infrared). This paper describes the design and the experimental results of the off- axis three mirror optical system which fulfills these requirements. The three mirror anastigmat consists of two aspherical concave mirrors and a spherical convex mirror. The design is configured for a telecentric flat focal plane.
