摘要
Abstract
A liquid contraband detector based on quasi-stationary electrical capacitance tomography is introduced. This instrument used MCU to control CDC chip further to complete capacitance detection, the corresponding dielectric constant was converted through the operation of MCU to judge whether of the tested liquid is contraband or not. It shows that 50% alcohol in a bottle with 4mm thickness can be alarmed by the instrument. Using this instrument, the contraband liquid can be found need not to open the bottle.关键词
