Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0021] figure 1 It is a block diagram of the geostationary orbit area array staring multi-spectral multi-mode imaging system of the present invention. Such as figure 1 As shown, the geostationary orbit area array staring multi-spectral multi-mode imaging system includes a main optical system 1, a light splitting element 2, a time-sharing filter device 3, a visible near-infrared focal plane assembly 4, and a mid-wave infrared focal plane assembly 5. The main optical system 1 collects the radiation information of the target and transmits it to the spectroscopic element 2; the spectroscopic element 2 separates the visible near-infrared spectrum from the mid-wave infrared spectrum in the target radiation information, and transmits the visible near-infrared spectrum to the time-sharing filter The optical device 3 converges the mid-wave infrared spectrum to the mid-wave i...

Abstract

The invention discloses a geostationary orbit surface array staring multi-spectral multi-mode imaging system, comprising: a main optical system, a light splitting element, a time-sharing filter device, a visible near-infrared focal plane assembly and a mid-wave infrared focal plane assembly; wherein, The main optical system collects target radiation information; the spectroscopic element separates the visible near-infrared spectrum from the mid-wave infrared spectrum, the visible near-infrared spectrum is transmitted to the time-sharing filter device, and the mid-wave infrared spectrum converges to the mid-wave infrared focal plane component; the mid-wave infrared focal plane component converts the light signal of the mid-wave infrared spectrum into the first electrical signal; The specified infrared spectrum is converged to the visible near-infrared focal plane component; the visible near-infrared focal plane component converts the optical signal of the specified visible near-infrared spectrum into a second electrical signal. The invention achieves the effect of staring multi-spectrum and multi-mode imaging of the geostationary orbital array.

Description

technical field [0001] The invention belongs to the technical field of remote sensing imaging, and in particular relates to a geostationary orbit surface array staring multi-spectrum multi-mode imaging system. Background technique [0002] Geostationary orbit satellites have a wide monitoring range, high time resolution, and extremely high responsiveness. Under ideal conditions with no clouds during the day, continuous observation, even video observation, of targets in the shooting area can be carried out, and it also has the potential of dynamic target detection and dynamic target indication. Through fast pointing control, satellites can conduct comprehensive observations combining large-scale real-time, continuous maneuvering imaging and high-time resolution imaging, and then can obtain higher spatial resolution and multi-spectral ground image information; Continuous observation, staring observation, regional imaging and mobile imaging, etc., play an important role in mee...
