Description
Summary:Method of none-destructive detection of tobacco filter capsule by Terahertz Time domain spectroscopy is proposed. Flavor capsule in the cigarettes filter contains liquid spices, which could help improving cigarette taste. The absence, location, and damage condition of filter capsule would affect the tobacco quality tobacco factory's economic benefit and credibility. Inline quality inspection of tobacco filter requires accurately locate the flavor capsules in the filter. The filter capsule perfectly matches THz spatial resolution. In experiment, transmission Terahertz time domain spectroscopy imaging system was employed to measure the tobacco filer capsule. The result show that two-capsules in the tobacco filter can be positioned and distinguished by THz transmittance imaging. The result shows that Terahertz technology is a promising application for tobacco filter capsule quality control and production efficiency improvement.
