Research On Aplication Of Little Pixel And High Transillumination Line Scan X-Ray Detector

At present, The development and application of X-ray has been popular around us.Unconsciously,it has become very important in our lives. The research of X-ray detector been never been stopped and it has been the rapid development. In the medical, industrial non-destructive testing, security areas and food testing field all of them need flexibility in the use of X-ray detector in order to achieve the intended purpose.The advancement of X-ray detector technology has played a decisive role in security inspection equipment. The performance and indicators of X-ray detector equipment directly affects the security of the final technological level.X-ray security detector, because of the powerful features of distinguishing objects’ shape and composition and the low price, has been used widely. X-ray security detector is an important part of security detection equipment,standing for the level of seience.In non-destructive testing field, the advances of X-ray detector have played a decisive role. It’s performance indicators directly affect the final results of the testing. Because the X-ray non-destructive testing equipment can detect whether the parts have defective characte-ristics or not with out destroy the parts. So, the X-ray products to the final success in this field. In food testing and the medical field, the X-ray detector is also very important position.Based on the reach of inland and oversea X-ray detection technology,.after the type I of DT-SCAN this paper definitudes the sense of the design of a new X-ray detector. Then this paper gives thecomposition of X-ray detector,and designs the photoelectric detection circuit of X-raydetector according to the theory of detection of weak signals.Then,this paper designs the hardware and software of the typical module of the embeded X-ray detector. Finally this design experiments to the funcation of X-ray security detector and then carries through the environmental testing. On the basis of this detection machine, after some deeper research, we can have a widely use in security and other important fields with the X-ray detector.
