A passive infrared dynamic image generation technology and related devices are proposed.The parameters of time constant, spatial resolution and radiation contrast of the device are theoretically analyzed and experimentally studied.The experimental results show that the spatial resolution of the converter is 6lp / mm, contrast ratio greater than 100: 1, time constant ~ 6m s. The obtained infrared images can be used for performance testing and calibration of various infrared imaging instruments and devices, as well as infrared imaging simulation experiments
