Embodiment Construction

[0030] Such as figure 1 Shown, the present invention it comprises:

[0031] 1) A method for identifying cigarette varieties and authenticity based on the relationship between different types of cigarette samples and the relationship between real and fake cigarettes of the same type and the visible light and near-infrared absorption spectra from the samples; Connect with the computer; the light source is fixed with a tripod bracket to adjust the viewing angle of the light source, and the matching power cord is connected to an external power supply; the spectrometer is fixed with a matching tripod bracket to adjust its height and viewing angle; the positions of the light source, the spectrometer and the cigarette sample are fixed. The light source is irradiated on the cigarette sample contained in the sampling container. After the spectrometer is calibrated by the white board, it receives the reflected and scattered light from the sample; the spectral image of the cigarette samp...

Abstract

A method of using visual light and near infrared spectrum to identify variety of cigarette nondestructively includes fixing halogen lamp on A - frame, using power supply wire to provide 220V power to spectrograph and light source as well as computer, connecting spectrograph to computer through data line for transmitting collected sample spectrum data to computer, applying spectrum special software of ASD View Spec Pro V2.4 and Unscramble V9.2 to carry out process and analysis on collected data then feeding analyzed data back to information platform for displaying variety of tested sample.

Description

technical field [0001] The invention relates to a method for identifying cigarette varieties and authenticity, in particular to a method for nondestructively identifying cigarette varieties and authenticity by using visible light and near-infrared spectrum technology. technical background [0002] With all kinds of cigarette products on the market, it is difficult for consumers to distinguish the quality of cigarettes and different cigarette products with the naked eye, and there are a large number of fake and shoddy products. [0003] Conventional chemical methods to identify different types of cigarettes have the disadvantages of long period and poor reproducibility. Contents of the invention [0004] In order to overcome the above existing problems, the object of the present invention is to provide a method for non-destructively identifying cigarette varieties and authenticity by using visible light and near-infrared spectrum technology. Not only can it quickly and rea...
