专利汇可以提供Optical-binary coded position-sensitive radiation detector专利检索,专利查询,专利分析的服务。并且A position-sensitive radiation detection system has been provided for use with scintillation detection mediums wherein the position of a radiation event within a block of scintillation material is determined by an optical-binary coding system such that a digital signal output is provided which is indicative of the position of a radiation event within the scintillator. The image of the scintillator is formed onto the light sensitive areas of a plurality of photomultiplier tubes by means of a corresponding plurality of lenses. A coded screen or mask is placed between each lens and its corresponding photomultiplier tube in the position of the image to obstruct a selected portion of the image from the view of each photomultiplier so that the output of each photomultiplier tube provides one digit of a multiple bit binary signal to indicate the location of the event. The first digit or least significant bit would come from a photomultiplier tube number one which would have a screen which obstructs one-half of the image so that the output would be either a binary ''''1'''' or ''''0'''' depending upon which half of the scintillator is struck by a single beam of ionized radiation to generate a light pulse with the detector medium. A second screen with two slits is placed in position of the image on a second photomultiplier tube to divide the image of the scintillator into four parts and forms the second bit of the binary signal, thereby dividing the images into four sections as would be coded at the outputs of photomultipliers one and two; and so on for additional photomultipliers. The screen may provide either rectangular or polar coordinate measurements and the outputs of the photomultipliers may be stored in a digital storage device or connected to an analog signal for oscilloscope display or other recording.,下面是Optical-binary coded position-sensitive radiation detector专利的具体信息内容。
