Sensor, influencing on system's performances, is one of some key techniques in x-ray industrial computed tomography (CT) systems. Instead of common sensors such as temperature, humidity, pressure and optic fiber, the sensor used for detecting x- or (gamma) -ray in industrial CT system, generally is called nuclear radiation detector, so that the radiation energy involved in tested information can be transformed into electric signals easy to be measured. Considering the existing problems for sensor (or detector) in CT systems, a new sensor is experimented by using optoelectronic integrated technique with optic fiber face- plate for optically coupling and transmission, and it is beneficial to the performances with high integrated, high efficiency, high resolution, miniaturized and low cost in industrial CT systems.
