The optical fiber type X-ray image enhanced sensor comprises a conversion screen, a photoelectric cathode, an image enhanced device, a fluorescent screen, an optical fiber, an imaging receiving device. The optical fiber technology is utilized to solve the problems of large imaging area and low image resolution. The imaging receiving device and the optical fiber coupling technology are utilized to solve the problems that images are viewed only by eyes; electric signals can not be output, and then the images can not be quantitatively measured; the noise of the images is large; the cost is high. The X-ray image enhanced sensor which has low cost and high resolution and is capable of outputting the electric signals and carrying out quantitative measurement by connected with a computer is provided. The optical fiber type X-ray image enhanced sensor can be widely used for industrial detection, lossless flaw detection and non-contact in-line detection of small objects, agricultural seed inspection, medical orthopaedics diagnosis, etc.
Description
The utility model belongs to field of photoelectric technology, relates to a kind of improvement that optical lens type radioscopic image is strengthened transducer.
Traditional optical lens-type radioscopic image strengthens transducer and mainly comprises conversion screen, photocathode, image intensifier, lens, receiver.It converts x-ray source to visible images by conversion screen and strengthens through the photocathode in the image intensifier, make visible images process lens imaging to receiver, because adopt the working method of optical lens to make that the imaging area of this transducer is bigger, then image resolution ratio is not high; Transducer can only pass through its image of receiver visualization, because it can not be exported the signal of telecommunication and then can't carry out quantitative measurment to image; The picture noise of transducer is big, cost is high.
The purpose of this utility model is that solution optical lens type radioscopic image enhancing transducer imaging area is bigger, cause image resolution ratio low, can not export the signal of telecommunication and then can't carry out quantitative measurment image, the problem that picture noise is big, cost is high provides a kind of low cost, high-resolution, can export the signal of telecommunication and be connected the radioscopic image enhanced sensor that carries out quantitative measurment with computer.
Detailed content of the present utility model: mainly comprise conversion screen 1, photocathode 2, image intensifier 3, phosphor screen 4, optical fiber 5, imaging receiving device 6, be characterized in: the photocathode 2 input end faces coupling in the substrate of conversion screen 1 and the image intensifier 3, phosphor screen 4 couplings in the input end face of optical fiber 5 and the image intensifier 3, the silicon chip coupling of the output end face of optical fiber 5 and imaging receiving device 6.Dynamic duty process of the present utility model: the illumination that x-ray source sends is on testee, and with the sensor alignment testee, the conversion screen 1 of transducer receives through the X-ray signal of testee and converts visible light signal to.By optical fiber 4 visible light signal is imaged onto photocathode 2, utilizes 3 pairs of darker figure image intensifyings of image intensifier; With fiber coupling technique optical fiber 5 and imaging receiving device 6 are coupled together, the image of enhancing is received by imaging receiving device 6 through optical fiber 5 and the output signal of telecommunication is connected with computer, and computer carries out quantitative measurment to image.
Good effect of the present utility model: adopt optical fiber technology, it is big to overcome the imaging area that prior art adopts lens arrangement to bring, and causes the low problem of image resolution ratio; Adopting image device and fiber coupling technique to overcome prior art can only its image of visualization, can not export the signal of telecommunication and then can't carry out quantitative measurment to image; The problem that picture noise is big, cost is high provides a kind of optical-fiber type radioscopic image to strengthen transducer.The online detection of industrial detection, nondestructive inspection and noncontact, agricultural seed check, the medical orthopaedics that can be widely used in wisp are diagnosed or the like.
