[Inspection of writing-time and script by FTIR microscope].
The IR spectra of different ball-pen script at different paper were determined by FTIR microscope and ATR objective. The spectra of different script on different paper in no time and in three-month time are compared. The result is showed that the most of IR spectra of different ball-pen are different and the IR spectra got in no time and in three-month time are different. The FTIR spectra can be used for inspecting scripts and help to inspect the writing-time.
