Problems solved by technology

However, the existing infrared imaging devices generally can only realize single-channel infrared imaging, and two independent infrared imaging devices are required to realize two-channel infrared imaging of the same band or different bands, which has the disadvantages of large volume power consumption, complex system architecture, and poor real-time performance. , The price is high, and it cannot meet the application requirements of real-time and image fusion display for multi-channel infrared imaging of the same band or different bands

Moreover, when the general infrared focal plane detector changes with the working time or ambient temperature, the non-uniformity of the focal plane array also drifts, and the infrared image correction effect will gradually deteriorate, which cannot meet the requirements of high-quality infrared imaging.
