With the development of infrared technology,infrared cameras are more and more used in military,security,medicine,agriculture and other fields. Since infrared scenes have the characteristics of large differences in infrared radiation,infrared cameras are usually required to have a perfect imaging performance of high dynamic range,in order to adapt to the needs of various scenes. This paper introduces the basic principle of typical high dynamic range infrared imaging technologyreported in the past 20 years and their characteristics.This paper also predicts the development trend ofhigh dynamic range infrared imaging technologyin the future period based on the current development status of it.
