Abstract

The field of art is loaded up with works of various painters that covers a tremendous market of art buyers. Recognizing real artworks from copies or fake art is a challenge. There have been various strategies to identify genuine works from fakes, however the field was for the most part dependent on the insightful eyes of art experts who committed themselves to the work and life of the artist(s). At present there are various ways to recognize real works like x-ray radiography, Ultraviolet fluorescence, infrared reflectography, painting sampling, carbon-14 dating, material weave check and so forth. In ongoing many years, Raman spectroscopy has drawn in expanding consideration in the field of craftsmanship examination. Inorganic and natural shades and furthermore restricting media, stains and varnish can be recognized in different objects of craftsmanship. Rather than examining the antiquities, Raman spectroscopy, being a non-destructive strategy, can be utilized for the immediate examination of small artefacts and gemstones. Bigger ancient rarities, like artworks, are not really effectively inspected without testing. In this manner, they can be analyzed through fiber optics Fourier Transform (FT) Raman examination of compositions. The colors in a few artworks could be recognized, despite the fact that they could be covered with a varnish layer. The laser beam is engaged through the varnish and the Raman signal of the colours can be distinguished. Raman spectroscopy is an optimal characterisation method for describing cultural materials as it is non-destructive, requires somewhat little sample preparation and uses short estimation times. Micro Raman is particularly helpful for looking at miniature examples and painting cross segments because of its spatial goal being adequately high to target singular color grains. Notwithstanding the non-damaging, miniature example examination benefits, there are limits to the utilization of Raman spectroscopy in the cultural legacy preservation setting. First and foremost, fluorescence is habitually seen in cultural materials. Besides, with the huge number of compositionally unpredictable and heterogeneous materials experienced in preservation, there is a requirement for cutting edge strategies that can manage enormous example datasets. It is the point of this MS Project Report to exhibit how Raman spectroscopy can give helpful data about artworks. We are motivated to do this in light of the fact that there has not been a lot of work in the field where craftsmanship, science and innovation have converged to recognize the validness of the artistic creations, particularly on Indian workmanship, and it was a chance to do something to the fields we are keen on. The critical target of this proposal is to utilize Raman spectroscopy and attempt to distinguish the approximate age of the compositions by utilizing the information.
