Embodiment Construction

[0027] The design and packaging of existing multi-spectral infrared detectors are mainly completed by mechanical coupling and physical splicing. The component structure is relatively complex, the process cycle is long, and the volume and weight are large. Higher requirements are put forward for the design of heat load and the selection of refrigerators. Requirements, and then affect the size and weight of the whole machine, based on the above practical problems, a new multi-spectral integration scheme is proposed, which integrates multi-spectral detection into the same infrared detector chip, and designs a partitionable selective transmission Light filters, and realize the precise correspondence between the chip partition and the filter partition. That is to say, this application integrates multi-spectral detection on the same infrared detector chip, and designs a filter that can be partitioned and selectively transmits light, and finally realizes the miniaturized packaging of ...

Abstract

The invention discloses an installation method of a multi-spectrum optical filter for an infrared detector and the infrared detector, and aims to integrate multi-spectrum detection on the same infrared detector chip, design an optical filter which can select light transmission in a partitioned manner, and realize miniaturized packaging of the multi-spectrum infrared detector. The integration level of the multi-spectrum infrared detector is improved, more effective information is obtained through partition and spectrum section detection, and therefore the problem that in the prior art, due to the fact that all spectrum sections are prepared respectively and integrated in a mechanical packaging coupling mode, the product structure of the multi-spectrum infrared detector is complex is effectively solved.

Description

technical field [0001] The invention relates to the technical field of infrared detection, in particular to a method for installing a multispectrum filter for an infrared detector and an infrared detector. Background technique [0002] In the field of earth resource exploration, infrared multispectral scanners are the payloads for obtaining information, while conventional infrared multispectral scanners require infrared detector components with multiple spectral bands. Therefore, the volume and weight of the infrared scanner load system are increased . Although with the maturity of infrared detector technology, by adopting the multi-spectrum integration method inside the infrared detector, the volume weight of the load can be greatly reduced, and the difficulty of optical design can be reduced. However, in the existing integration technology, each spectral band is prepared separately, and then integrated by mechanical packaging and coupling, which leads to a complicated pro...
