The Purity Detection Method of Gem Material Based on the Echo Reflection

Abstract:

In traditional purity detecting system, the purity of gem is determined by depending on the obtained shape of the reflection spectrum and the different shape features. Once gem is mixed, the system cannot accurately identify the aliasing and deformation reflection spectrum, and the accuracy rate of detection is low. A detection system for the purity of gem based on aliasing spectrum splitting algorithm is proposed. By extracting the detection spectrum characteristic parameter of the gem, the superposition and correlation for spectrum characteristic parameter is calculated; aliasing spectrum information is made splitting to classified achieve the purity detection of gem. Experiments show that this method improve the accuracy rate of the purity detection, and achieves satisfactory results.
