X-Ray Image Device Based on Optical Fiber Taper Coupling
Using the nondistortion transport property of optical fiber taper and taking it as the optical relay component,X-ray image intensifier and charge coupled device (CCD) are coupled into X-ray image device by photosensitive adhesive as the coupling medium. The influences on coupling efficiency of optical fiber taper and CCD coupled by the coupling medium of air and photosensitive adhesive are analyzed,the coupling crafts are discussed and the key coupling techniques are given out. Experiments show that the spatial resolution of X-ray image device can reach as high as 3.5 lp/mm,which has good perspective images of human body and can meet the demands of small medical imaging as well as nondestructive testing.
