Technical Field

Background

Many documents in economic and civil cases need to judge the juju-mo timing sequence to determine the fact of the case. When some special documents or important documents are formed, the characters must be written or printed firstly, and the official seal stamp is printed after the characters are checked without errors, namely, the characters are printed firstly and then the characters are printed. When a person counterfeits such documents, the person who wants to counterfeit takes an abnormal means to steal the seal and then write the characters, namely the document forming process is in an inverted sequence, the person who wants to counterfeit documents is identified by the jube sequence, and the person who wants to counterfeit documents is identified by identifying the sequence of the seal and other handwriting on the documents in economic and civil cases.

At present, the identification of the vermilion ink time sequence of the document is usually directly observed by using a microscope, and the traditional method is unreliable and is very easy to misjudge.

And (3) observing the imaging of the ocular lens, and adjusting the focusing knob until the focusing surface of the detected file seen by the ocular lens is clear. Then, the zoom body on the microscope is adjusted, and the zoom body is magnified by a proper time. Then, the LED lamp of the base is turned off, the indoor light is turned off, the blue fluorescent module is turned on, and the brightness of the blue fluorescent module is adjusted. The light emitted from the blue fluorescent module is irradiated onto the document through a color filter (not shown) of a specific wavelength band and an objective lens in sequence. The color filter with specific wave band filters light with wave band from 460nm to 490nm, so that the rest light with wave band from 460nm to 490nm irradiates to the cross of the seal and the character (signature). Under the illumination of a wave band of 460nm to 490nm, the stamp-pad ink of the stamp can emit strong fluorescence, and the printed and handwritten writing does not emit fluorescence, so that the fluorescence state of the crossed part of the vermilion ink can be observed through an eyepiece, and the fluorescence state of the crossed part of the vermilion ink is shot through a microscope camera, so that the forming sequence of the stamp and the writing can be more reliably identified.
