Abstract

The invention provides a filter type two-waveband small ultraviolet omnidirectional imager system, relating to the field of an optical machine. The system comprises two ultraviolet wide waveband imagers, a narrow band filter, a filter wheel and a stepping machine, wherein each ultraviolet wide waveband imager comprises an N pyramid reflector, a wide waveband ultraviolet lens group, a CCD (charge coupled device) detector and an electronics system, wherein the wide waveband ultraviolet lens group, the CCD detector and the electronics system are arranged in front of the N pyramid reflector in sequence; the CCD detector is connected with the electronics system; a narrow band filter is arranged between the wide waveband ultraviolet lens group and the N pyramid reflector; the stepping motor is arranged between the two ultraviolet wide waveband imagers; the filter wheel is arranged on the stepping motor; and the narrow band filter is arranged on the filter wheel. The system uses the high-performance narrow band filter and the ultraviolet wide waveband imagers to perform large-range high-resolution detection on the atmosphere in the ultraviolet band under the star and in limb direction. The system is suitable for detecting the high space-time coverage of the middle atmosphere and near space.

Description

technical field [0001] The invention relates to the field of optical mechanics, in particular to a filter-type dual-band small-sized ultraviolet omnidirectional imager system. Background technique [0002] Limb observation technology is a way to measure atmospheric trace gases using optical instruments working in outer space. It combines the high spatial coverage of traditional nadir observation with the high vertical resolution and high observation accuracy of occultation observation. State-of-the-art technology for atmospheric sounding. Most of the atmospheric limb observation instruments in the ultraviolet band designed abroad are spectrometers or imaging spectrometers. The spectrometer or imaging spectrometer observes a specific limb direction of the atmosphere, which can provide rich spectral information of the observation area, but the observation area is limited by the optical structure, and the area is limited, so it is impossible to conduct large-scale, wide-band, ...
