摘　　要：在文件检验中,黑白红外线照相是一种检验变造文件的方法,然而,在某些情况下效果欠佳。为了提高检验的准确性,不妨可以应用红外线合成图像的方法。应用Photoshop图像处理方法,根据红外线彩色照相的感光原理和色彩再现过程,对数码照相机拍摄的可见光图像和红外线图像进行适当处理,即可生成红外线合成图像。这种图像可以反映字迹对可见光和红外线的吸收与反射情况,通过判断字迹颜色有否改变来检验书写色料的异同。由此可见,利用红外线合成图像方法检验某些变造文件,可以获得黑白红外线照相无法得到的检验结果,这对提高鉴定结论的准确性具有实际应用价值。Infrared color photography records both the images created by visible light and infrared, which has several advantages compared with the infrared black-white photography. For various reasons, its application in forensic identification is still a virgin land. In accordance with the principle of light sensitivity and color representation, the visible light images and infrared images are merged to create infrared composite images. In color presentation, these composite images and infrared color images are technically identical. It is proven to be an effective tool to identify false document by utilizing infrared composite photography.
