Optical Design of Wide FOV Infrared Scanning Imaging System

Infrared scanning imaging system provides the user with an effective means of achieving imaging situational awareness. This paper present an aperture stop re-imaging optical system for infrared scanning imaging system to achieve high-resolution, wide FOV imaging. As an example, optical system with operating waveband of 8～10 μm, effective focal length of 520 mm, and imaging FOV of 1.4°×72° is also presented. The design results indicate that the optical system has perfect performance and can be used in many military and civil applications.
