Research on temperature drift compensation correction algorithm for VOx uncooled infrared detector

The temperature drift of uncooled focal plane infrared detectors mainly comes from the additional resistance changes caused by Joule heating during detector operation. Therefore, this article proposes algorithmic correction for the temperature drift of 12 μm vanadium oxide uncooled infrared detectors. In order to ensure stable and coherent output, a temperature drift error correction model is established based on linear model algorithm, and finally a temperature drift compensation formula is given.
