Abstract
A visible, MWIR, long focal, oblique view and focusing optical system of aerial camera is described, and in this paper we design an innovative optical system with common optical path and catadioptics configuration. The focal length of this optical system is 1.45m in the visible waveband (0.7~0.9μm,) and 0.61m in MWIR waveband (3.7~4.8μm), and the oblique view scanning range is within 20km~100km. To meet the requirements for the sharp imaging quality under the circumstances of high altitude environment and real time variable range, this aerial camera is focused by making back cutoff length longer to add a mirror, then MTF of optical system is all above 0.4 in Nyquest frequency.
