对于经常需要将文字或图片资料转 换成电子文件进行编辑处理的人来说, 扫描仪由于其合理的价格和简便的操 作,己逐渐为人们所接受。然而,对于 那些从事摄影、印刷等工作的专业人士 来说,一般的单镜头扫描仪已不能同时 满足他们对超高解像度和较长使用寿命 的需求。于是,更高品质的采用双镜头 技术的扫描仪应运而生。 传统的单镜头技术,扫描仪内部只 有一个镜头。为适应多种扫描用途的需 要,镜头会发生移动,从而使光路产生 变动,影响扫描的清晰程度,长期使用 还会导致镜头的磨损,降低扫描仪的使 用寿命。举例来说,某记者,有时需要 将稿件直接印刷出版,而有时又要将其 存入电脑以发送电子邮件。当进行四色 或六色(高保真)印刷时,他需要进行 高解像度的扫描,以确保印刷质量;而 For those who often need to convert text or picture materials into electronic files for editing, the scanner has become increasingly accepted for its reasonable price and ease of operation. However, for those professionals engaged in photography, printing and other work, the common single-lens scanner can no longer meet their needs for high resolution and long service life. As a result, higher quality dual-lens technology scanner came into being. Traditional single-lens technology, the scanner only one inside the lens. To meet the needs of a variety of scanning applications, the lens will move, so that the light path changes, affecting the clarity of the scan, long-term use will lead to lens wear and reduce the life of the scanner. A journalist, for example, sometimes needs to print and publish the manuscript directly, sometimes with a computer to send an e-mail. When performing four- or six-color (high fidelity) printing, he needs high-resolution scanning to ensure print quality; and
