Embodiment Construction

[0027] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, using a single-band 256×1 linear focal plane device as a sub-module:

[0028] The ultra-long line focal plane device of the present invention consists of a splicing substrate 1 inlaid with a ceramic transition plate 3, an odd-numbered sub-module 6, an even-numbered sub-module 4, a cold filter window frame 8 with an optical filter 9, and an odd-numbered module outer lead strip 7. The even-numbered modules are composed of 5 and other components.

[0029] The splicing substrate 1 is made of a metal material with low thermal expansion coefficient and is inlaid with a ceramic transition plate 3. The surface parallelism and flatness of the splicing substrate and the ceramic transition plate are better than 0.005mm. There are a series of screw holes 2 necessary for installing cold filter window frame 8, outer lead straps 5, 7 and other parts on the s...

Abstract

This invention discloses a super long line infrared focal plane detector, which is formed by rotating multiple sub-modules to be crossly fixed on a spliced base plate to form the splice without leakage, in which, the sub-modules are small line infrared focal plane detectors of 256x1 or 512x1, which can be either single wave band or double wave band.

Description

technical field [0001] The invention relates to an infrared focal plane detector, in particular to an ultra-long line-row infrared focal plane detector spliced ​​by multiple sub-modules. technical background [0002] Infrared detection technology plays an extremely important role in military, industrial and civilian fields such as earth observation, aerial reconnaissance, meteorology, geomorphology, environmental monitoring, and resource survey. It is a comprehensive high-tech technology. In the field of aviation and aerospace infrared remote sensing technology, its main development directions are: on the one hand, improving the photoelectric performance of infrared detectors and improving detection sensitivity to obtain richer target information; on the other hand, expanding the scale of infrared detectors, that is, increasing The number of infrared sensitive elements to improve the spatial detection resolution of the infrared system. Because for the instrument platform an...
