Problems solved by technology

[0002] At present, the detection device with very small interface concentration of pollutants has the problems of easy loss of information, unstable performance, and unsafe operation, and the environment required by the detection device is very harsh.
[0003] In the article Determination ofInterfacial Concentration of a Contaminated Droplet from Shape OscillationDamping, Frenchman Benjamin Lalanne discussed the mechanism of the contaminated droplet interface, and numerical simulation analyzed the decomposition of the contaminated droplet into a Legendre function mode, but did not provide a detection device that can realize the use of entanglement sources and linear system resonance elastic damping characteristics

Abstract

The invention relates to an entanglement source and linear damping polluted liquid drop detection device. The device comprises an entangled source emitter, a quarter-wave plate, a polarization beam splitter, a target chamber, a control linear damper, a vacuum controller, a polluted liquid drop controller and an information processor, wherein the polluted liquid drop controller is used for drippingpolluted liquid drops to be detected into the target chamber; the two sides of the target chamber are provided with a transparent incident window and a transparent emergent window respectively; the vacuum controller is used for vacuumizing the target chamber; the linear damper is controlled to input inert gas into the target chamber; an entangled photon pair emitted by the entangled source emitter sequentially passes through the quarter-wave plate and the polarization beam splitter and then is divided into two beams of light; and one beam of light enters the target chamber through the incident window, irradiates to-be-detected polluted liquid drops and then is emitted out through the emergent window; and the information processor is used for generating a coherent spectrum image accordingto the light beam carrying the detection information and emitted by the exit window and the other light beam passing through the polarizer. According to the invention, the detection information is richer, the detection process is more stable, and the detection accuracy is improved.
