快速扫描仪与普通扫描仪的扫描原理相同,但在技术和硬件方面是有很大区别的,主要表现在以下几个方面:●快速扫描仪一般采用独立开发的控制器专用集成芯片(ASIC);●快速扫描仪采用高速CCD,普通扫描仪采用的CCD采样率仅达1Mhz,而高速CCD的采样率达到4～10Mhz; Scanners and ordinary scanners scan the same principle, but in terms of technology and hardware are very different, mainly in the following areas: Fast scanners commonly used in the development of controller-specific integrated chip (ASIC) ; ● Fast scanners using high-speed CCD, CCD scanners commonly used sampling rate of only 1Mhz, and high-speed CCD sampling rate of 4 ~ 10Mhz;
