Research On The Parameter Measurement System Of The Scanning Infrared Optical System

The conical scanning infrared optical system is a commonly used technique in the infrared detection guidance technology, mainly used in tactical missile seekers and airborne infrared search and track systems. It is difficult for the conical scanning infrared optical system to be assumed and detected, because the conical scanning infrared optical system is different from the traditional visible light system. Hence, research a parameter measurement system of the conical scanning infrared optical system has great significance for us to improve the alignment accuracy of the conical scanning infrared optical system, and to ensure the guidance precision of infrared seeker.In this dissertation, the main components and operating principle of the parameter measurement system of the conical scanning infrared optical system are introduced. The function and design features of the subsystems are explained in detail, and the blue print is completed. The adjustment methods of the infrared collimator are discussed, and the stray light analysis has been done by using the FRED software in allusion to the no ideal imaging. Mica-glass board is used to suppress the stray light, and the effect is very good. Finally, the accuracy of the parameter measurement system of the conical scanning infrared optical system is analyzed and practical tested.
