This paper introduces how to determine and analyse the resolution and functions of the relevant parameters of the film scanner of QSS-2901 digital photographic printer by testing experiments. In this way, it lays the foundation of high quality film scanning operation. 本文介绍了如何通过实验对QSS-2901数字彩扩机底片扫描仪的扫描分辨率及其相关参数功能进行初步测定和分析,为高质量地完成底片扫描奠定了基础。
In high-property film scanner, a charge coupled device refrigeration constant temperature system is composed of the temperature sensor, the semiconductor cooler, the programmable PWM impulse generator, the radiator and the fan. 在高性能胶片扫描仪中,CCD恒温制冷系统可以由温度传感器、半导体制冷器、可编程PWM脉冲发生器、散热片和风扇等组成。
A Study on the Film Scanner(FS) of QSS-2901 Digital Photographic Printer QSS-2901数字彩扩机底片扫描仪浅析
Its hardware is composed of a film scanner ( or a laser digitizer ), a PC computer and a hardcopy unit, which are common in most of the radiation oncology departments. 它由扫描仪(或激光数字化仪)、胶片剂量仪软件和微机以及硬拷贝输出设备构成。
The traditional way of catching image is to input CT film to computer by scanner, which brings us noises artificially and worsens the image effect. 传统的图像获取方法是将CT胶片通过扫描仪输入到计算机,但这种方法人为的带来了噪声,影响了图像的质量。
