Abstract

The invention relates to the technical field of optical testing, in particular to an infrared dynamic scene simulator based on a miniature Peltier array. The infrared dynamic scene simulator comprises a control computer, a drive circuit, the miniature Peltier array and a projection lens; the control computer is connected with the drive circuit through a VGA connector, the drive circuit is connected with the miniature Peltier array through an addressing line, and the miniature Peltier array is placed on a focus plane of the projection lens; the control computer is used for generating a video matrix analog signal and sending the signal to the drive circuit; the drive circuit is used for analyzing the video matrix analog signal, conducting analog-digital conversion, and then sending a digital drive signal to the miniature Peltier array; the miniature Peltier array generates a temperature field distribution image and radiates the image to the projection image; and the projection lens generates vignetting-free infrared dynamic scenes at infinite regions. By means of the infrared dynamic scene simulator, low-temperature high-resolution infrared dynamic scene simulation can be achieved, low temperature infrared dynamic scene simulation accuracy is effectively improved, and the testing requirements of different guide heads are met.

Description

technical field [0001] The invention relates to the technical field of optical testing, in particular to an infrared dynamic scene simulator based on a miniature Peltier array. Background technique [0002] The infrared dynamic scene simulator is the most important simulation test equipment used in the laboratory simulation test process using the infrared imaging seeker. The infrared dynamic scene simulator can simulate the infrared scene information of the target actually observed in the actual combat process of the infrared imaging seeker, and form a static or multiple continuous infrared scene images, which can be used in the early design and mid-term test process of the infrared imaging seeker In the process, the precise and expected evaluation of the combat effect of the infrared imaging seeker was found to be insufficient for cyclical improvement design, reducing development iterations, and shortening the development cycle. [0003] Infrared dynamic scene simulation t...
