Abstract

The invention relates to the technical field of jade detection, in particular to a jade identification method based on a terahertz time-domain spectroscopy technology. The method comprises the following steps: S100, establishing a jade classification identification model; S200, preparing a to-be-identified jade sample; S300, measuring a terahertz time domain signal of the to-be-identified jade sample; S400, calculating characteristic parameters of the to-be-identified jade sample; and S500, comparing the characteristic parameter of the to-be-identified jade sample with each model in the jade classification identification model to obtain an identification result. To be specific, the S100 includes: S101, preparing a natural jade sample and an artificially processed jade sample; S102, measuring terahertz time domain signals of the natural jade sample and the artificially processed jade sample; S103, calculating characteristic parameters of the natural jade sample and the artificially processed jade sample; and S104, on the basis of the characteristic parameters, forming a jade classification identification model based on the characteristic parameters. With the provided jade identification method based on the terahertz time-domain spectroscopy technology, problems of incomprehensive detection and low efficiency in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of jadeite identification, in particular to a jadeite identification method based on terahertz time-domain spectroscopy technology. Background technique [0002] Jadeite is a mineral aggregate composed of various minerals mainly jadeite. Jadeite is known as the "King of Jade". Because of its fine texture, compactness and toughness, warm color, soft and elegant, it has been loved by the world for thousands of years. The mineral particles of jadeite often have impurities such as iron and manganese, resulting in black, gray, brown, yellow and other variegated colors, which greatly affect the beauty of jadeite and reduce the value of jadeite. In order to remove these variegated colors At the same time, to add the color of jadeite, people use chemical reagents to artificially process it to achieve bleaching, filling, dyeing and other operations. The quality of low-quality jadeite will be improved after manual tre...
