摘要

测量香芹酮和柠檬烯的液体二元混合物的浓度是目前制药、食品和香水行业生产产品的兴趣所在。提出了一种放置在传统光纤末端的法布里-珀罗干涉仪，用于快速和廉价的浓度测定。干涉仪腔由PDMS和两个反射Al表面组成。测定了柠檬烯混合物中香芹酮体积分数为0 ~ 100%时光的时域干涉。从依赖性来看，不同体积分数的溶胀率和溶胀时间不同。我们测量了选择的干扰极值的时间延迟来确定二元混合物中香芹酮的浓度。得到的时间延迟值范围从纯柠檬烯（体积分数为0%）的0.445 s到纯香芹酮（体积分数为100%）的11.386 s。由此可见，给定的方法可以在测量开始后的几十秒内获得浓度结果。

Optical fiber-tip sensor for detection of carvone and limonene ratio in liquid binary mixture

The measurement of the concentration of a liquid binary mixture of carvone and limonene is currently of interest in producing products in the pharmaceutical, food, and perfumery industries. A Fabry-Perot interferometer placed at the end of a conventional optical fiber is proposed for rapid and inexpensive concentration determination. The interferometer cavity consists of PDMS and two reflective Al surfaces. The time-domain interference of light for volume fractions from 0 to 100 percent carvone in the limonene mixture was measured. From the dependences, a different swelling rate and a different swelling time for the particular volume fractions are observed. We measured the time delay of selected interference extremes to determine the concentration of carvone in the binary mixture. The obtained values of the time delays range from a value for pure limonene (volume fraction 0 percent) of 0.445 s to a value for pure carvone (volume fraction 100 percent) of 11.386 s. It follows that the given methodology makes it possible to obtain a concentration result within a few tens of seconds from the start of the measurement.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
