Embodiment Construction

[0042] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0043] Such as figure 1 As shown, the present invention provides a spaceborne multi-probe ionospheric imager device, which solves the problems of small instantaneous field of view, low time resolution of multi-channel detection, and poor reliability of moving parts of the spaceborne imager.

[0044] The spaceborne multi-probe ionospheric imager device includes: a first camera 1 , a second camera 2 , a third camera 3 , a photometer 4 , and a main frame 6 . The three cameras and the photometer 4 are all fixed on the main frame 6 .

[0045]The first camera 1, the second camera 2, and the third camera 3 have the same structure but work in different wavelength bands, forming imaging of different channels for the ionosphere; the working band of the first camera 1 is 135.6±5nm; the second camera 2. The working waveband is 140-160nm; the working waveband...

Abstract

The invention belongs to the technical field of spatial light detection and satellite-borne detection devices, and particularly relates to a satellite-borne multi-probe ionosphere imager device whichcomprises a first camera, a second camera, a third camera, a photometer and a main frame, wherein the first camera, the second camera and the third camera work in different wave bands to form imagingof different channels for the ionosphere; the photometer is used for measuring the illumination intensity in the field of view and judging day-night alternation; and the main frame is used for fixingthe three cameras and the photometer and providing a heat dissipation function. By the adoption of the device, the problems that the reliability is poor due to the fact that ionosphere detection needsoptical filter wheel switching, and the detection time of different channels is inconsistent are solved.

Description

technical field [0001] The invention belongs to the technical field of space light detection and space-borne detection devices, and in particular relates to a space-borne multi-probe ionospheric imager device. Background technique [0002] The ionosphere is one of the most important areas for human space activities. It is an area formed by partial ionization of the earth's neutral atmosphere at an altitude of about 60-1000 km from the ground under the action of solar X-rays, EUV and other radiation. In this region, in addition to the neutral atmosphere, there are a large number of free electrons and ions that can significantly affect the propagation of radio waves. [0003] With the maturity of remote sensing technology and the increasing number of human spaceflight activities, the ionosphere is more and more closely related to human life. Radio communications, broadcasting, satellite navigation, radar positioning, etc. are mainly concentrated in this area. Ionospheric stor...
