Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to a jewel photoluminescence device and an image acquisition method thereof. Background technique [0002] With the continuous development of my country's economy and the upgrading of the consumption level of the people, jewelry, as a product that can meet spiritual needs, is increasingly favored by consumers. At present, China is the world's largest consumer of inlaid jewelry. The subsequent product quality problems are also increasing. For example, in order to obtain huge profits, unscrupulous merchants replace natural, high-value gemstones with artificial, low-value gemstones in inlaid jewelry to obtain the price difference. [0003] Luminescence detection is an important testing item in jewelry inlaid jewelry. The inspector can choose a certain range of ultraviolet light sources to irradiate gemstones to obtain the luminescence characteristics of gemstones. Area and o...

AI Technical Summary

Problems solved by technology

[0004] Because of the high radiation intensity of ultraviolet rays, direct contact with human skin will cause redness, swelling, pain and other phenomena. If exposed for a long time, it may cause skin cancer or tumors; at the same time, ultraviolet rays can also damage the eyes. Inflammation, keratitis, etc., long-term exposure to ultraviolet rays with the eyes is likely to induce cataracts

[0005] At present, the jewelry testing industry usually uses a sample box device spliced ​​by hexahedral UV-resistant material plates for luminescence testing, but this type of device has many defects and deficiencies, such as: 1. The structure is simple, and most of them are directly welded to metal plates; 2. The hatch is push-pull or open, so the operation is inconvenient and the hatch is easy to be damaged; 3. When used with other test accessories, due to the lack of design, it may cause the leakage of ultraviolet light source, thus causing damage to the human body

4. Due to the limitations of space design, it is not suitable for multi-angle detection requirements of inlaid jewelry
