The development of infrared technology is marked by the development of infrared detectors, and its development trend can be inferred from the development of infrared detectors.

1 The development of infrared focal-level devices to large-scale integrated devices with high-density and fast-response pixels reaching 10-10 yuan, from two-dimensional to three-dimensional multi-level structures, can realize high-definition thermal imagers in applications, greatly Reduce the size of the whole machine and enhance the function.

2) The development of dual-color and multi-color infrared devices enables the whole machine to simultaneously realize multi-light imaging detection of different wavelengths, multiplying the amount of system information and becoming an effective means of target recognition and photoelectric countermeasures.

3) The detector realizes the neural network function on the focal plane, and performs logical processing according to the program, so that the infrared machine can be intelligentized.

4) Increase the working temperature of the detector. High-performance room temperature infrared detectors and focal plane devices are one of the key points of development. No cooler is required, which will make the whole machine more compact and reliable, so as to achieve full solid state.

5) Improve the yield and reduce the price.

Current infrared imaging techniques do not take full advantage of the various properties of infrared radiation. With the development of detection technology and sensor technology, the precision and sensitivity of infrared detection are getting higher and higher, and people's requirements for recording and reproducing the real environment are getting higher and higher, and the detection technology is required to achieve a comprehensive monitoring of the environment. At present, most of the infrared reconnaissance equipment equipped in various countries in the world can provide two-dimensional space information of the target by detecting the infrared radiation of the target, but the distance information of the target cannot be determined. Therefore, with the continuous improvement of the requirements for the accuracy of environmental spatial parameters, it has become more and more important to expand the spatial distance information and find appropriate real-time and accurate three-dimensional spatial information acquisition methods. Therefore, people try to find some new methods to improve the signal-to-noise ratio between the target and the background signal, improve the accuracy and clarity of the detection of specific targets in specific environments, and obtain more abundant target information. This is what scientists continue to explore. The driving force behind a novel infrared imaging mechanism. Scientists seek new imaging methods from the characteristics of different frequency bands, amplitudes, phases and polarizations of infrared signals, and some new infrared imaging technologies are constantly being researched.
