电荷耦合器件(CCD)于七十年代出现以来,为作一种新型的摄象器件,它使象感技术发生了重大变化,目前这种固态象感器已经广泛应用于可见光,微光和红外波段。CCD器件具有动态范围大、灵敏度高及分辨率高的特点,这对于图象输入设备是十分有用的。本系统采用我院红外研究室研制的CCD摄象机作为输入机。设计了专用接口和控制软件,可任意输入图象中的某一区域。实验表明:此方案可行,系统已通过鉴定并已投入运行。
Since its emergence in the 1970s as a new type of imaging device, CCD has undergone major changes in image sensing technology. At present, such solid state image sensors have been widely used in visible light, low light and infrared Band. CCD devices have the characteristics of large dynamic range, high sensitivity and high resolution, which is very useful for image input devices. The system uses our hospital infrared laboratory developed CCD camera as the input machine. Designed a dedicated interface and control software, can enter any area of the image. Experiments show that this scheme is feasible, the system has passed the appraisal and has been put into operation.
