Abstract

A new type of optical system for atmospheric detection is designed by using the principle of panoramic imaging. Compared to the traditional ones, this optical system can observe nadir view and omnidirectional limb view at the same time, thus improving the efficiency and accuracy of the observation data inversion. The optical system consists of a front lens group, a panoramic annular lens, a relay lens group, and a narrowband filter. The nadir view and limb view are shared with the panoramic annular lens and the relay lens group. The narrowband filter is employed to select the specific band and restrain the stray light outside the band. This detector can monitor atmosphere conditions in the nadir field of view of 10° and the limb field of view of $360°\times (70.9°–73.3°)$. Based on this optical design, we develop a prototype for the detector and use it for the field test. The results of experiments verify the feasibility of the optical system design.
