Abstract

The invention relates to a dual-mode detector pixel sharing a readout circuit. The pixel comprises a dual-mode bridge floor layer, a substrate and a dual-mode readout circuit arranged on the substrate. The dual-mode readout circuit comprises a first branch and four second branches which are respectively provided with a control switch; and the four corners of the dual-mode bridge floor layer extend out of edge bridge legs respectively, a center bridge leg extends out of the center of the bridge floor, the first branch is electrically connected with the two opposite edge bridge legs, and the four second branches are electrically connected with the center bridge leg and electrically connected with the four edge bridge legs in a one-to-one correspondence mode. In addition, the invention also relates to an uncooled infrared detector adopting the dual-mode detector pixel and a use method of the uncooled infrared detector. Through the special design of the readout circuit, the same readout circuit can realize two imaging working modes with different array sizes and different pixel sizes, the application range of the pixel and the detector is effectively expanded, the specification types of the detector can be reduced, and the preparation cost and the use cost are decreased.

Description

technical field [0001] The invention relates to a dual-mode detector pixel unit sharing a readout circuit, a non-cooling infrared detector using the dual-mode detector pixel unit and a method for using the non-cooling infrared detector. Background technique [0002] Infrared detectors are widely used in the fields of security, national defense and health care. It is divided into cooled infrared detectors and uncooled infrared detectors. Among them, uncooled infrared detectors are Low-level advantages are more and more widely used; at present, uncooled infrared detectors are not only widely used in national defense and military fields, but also in civilian fields. Different application places have different requirements for uncooled infrared detectors. For example, in some special places, uncooled infrared detectors are required to have large area arrays, small pixel imaging, and clearer resolution; Increased production costs and use costs.
