Abstract

The invention belongs to the technical field of infrared imaging, and particularly relates to a split type uncooled infrared core assembly. The split type uncooled infrared core assembly solves the problems of limitation and defects of an existing split type uncooled infrared core assembly in small-size and low-power-consumption applications. The core assembly is of a split structure, specifically, the whole core assembly is divided into two parts. An infrared detector and a reading circuit thereof are the first part, and the function of detector signal reading is achieved. An infrared image preprocessing circuit and a power supply extended interface circuit are the second part, and the function of image preprocessing and interface output is achieved. Compared with the prior art, the splittype structure is adopted, only the detector and the reading circuit are arranged at the front end, so that the size and power consumption are reduced, and the requirements of application limited bysmall size are met.

Description

Technical field [0001] The invention belongs to the field of infrared imaging technology, and specifically relates to a split uncooled infrared movement assembly. Background technique [0002] The infrared movement component is an important part of the infrared imager. The uncooled infrared movement assembly generally consists of uncooled infrared detectors, infrared detector readout, infrared image preprocessing, power supply and interface output circuits. The infrared detector readout circuit is responsible for providing the necessary interface timing and power supply voltage for the detector; the infrared preprocessing circuit is responsible for realizing image processing functions such as non-uniformity correction, blind cell replacement, and image display enhancement; the power supply and interface output circuit is responsible for the machine The core provides secondary power supply and external interface functions. The existing uncooled infrared core components all adopt...
