Abstract
This is to report the principle of data scanning and the distinctive features of the infrared image scanner that We have recently developed. The infrared image scanner has been developed by modifying the already marketed flathead type image scanner to visualize invisible information by infrared light. This paper will report some features of the infrared image scanner, comaprered with conventional infrared video camera, and conventional image scanner. In addition, the verified results of practical application of the scanner in the field of archaeological study are also included in this report. And more, this image scanner will be effective tool to get only “Carbon” image (i.e. the image which is dawn by pencil) from the colorfull documents.
