In order to obtain the image detected by the IR

the data acquisition and processing system is designed.Data acqusition program is acquired using IDL according to the specification of the IR detector.Radiant quantity is transformed to the output of detector from radiant quantity of object.The raw infrared image is obtained according to the gray value of pixels.The purpose of using IR visualizations is achieved.The experimental results show that the data acquisition and processing system collects good image signal.It also proves this system meet the requirement of design.
