The invention discloses an ancient calligraphy and painting breakage-proofing and repairing system and method based on femtosecond laser technology. The system comprises a working platform, a glass substrate, a CCD camera, a femtosecond fiber laser, a real-time monitoring system and a control center, wherein the CCD camera, the femtosecond fiber laser and the real-time monitoring system are in signal connection to the control center; the control center is used for controlling the glass substrate and the femtosecond fiber laser to move by virtue of first shaft rising and second shaft rising, and the CCD camera, in combination with the femtosecond fiber laser, can be used for acquiring data about an ancient calligraphy and painting defect position; and the real-time monitoring system is used for acquiring the morphology features of an ancient calligraphy and painting pigment layer. The system and the method disclosed by the invention can be used for solving the problems of a conventional ancient calligraphy repairing process like not high repairing precision, complex process, high probability of damage to ancient calligraphy and painting and the like, and can be used for achieving precise positioned repairing, improving cleaning efficiency and guaranteeing the integrity of the ancient calligraphy and painting; and the system and the method can be used for achieving the real-time monitoring of the ancient calligraphy and painting, so as to avoid cracking and like damage of the ancient calligraphy and painting.
Description
technical field [0001] The invention relates to the technical field of protection of ancient calligraphy and painting, in particular to a system and method for preventing damage and restoration of ancient calligraphy and painting based on femtosecond laser technology. Background technique [0002] Ancient calligraphy and paintings will be damaged to varying degrees and unpredictable over time. At present, there is a shortage of talents in the ancient calligraphy and painting restoration industry. Restoration mainly includes: washing, unmounting, fate paper and full color. These links complement each other. Any problem in any of them will affect the value of the original work. Traditional repairs often damage artworks and are difficult to repair with the naked eye. Therefore, there is an urgent need for more effective and high-precision ancient calligraphy and painting restoration methods. [0003] Additive repair manufacturing technology is an additive manufacturing method ...
