摘要

在本文中，我们介绍了具有非接触式智能手机询问功能的磷光光纤准分布式传感器的工作原理、制造和性能。短强波纹长周期光栅（C-LPG）阵列被用作空间定位和激发磷光体的平台，磷光体的时间响应与温度有关。C-LPG 阵列是用脉冲 CO2 激光器制作的。准分布式传感阵列由紫外 LED 激发，智能手机测量的归一化差分上升/衰减时间响应可用作温度测量。传感点的体积小于 0.5 μL，间距从几毫米到几米不等，可同时或依次进行检测。对温度的响应和灵敏度进行了测量。结果表明，该传感阵列可以测量空间温度的突变和渐变，以及 0 °C 至 100 °C 范围内的随时间变化的过程，测量时间为 1 秒。

Smartphone-Readable Optical-Fiber Quasi-Distributed Phosphorescent Temperature Sensor

In this paper we present the principle of operation, fabrication and performance of a phosphorescent optical-fiber quasi-distributed sensor with contactless smartphone interrogation. An array of short strong corrugated long-period gratings (C-LPG) is used as a platform to spatially locate and to excite the phosphors whose time responses are temperature-dependent. The C-LPG array was fabricated using a pulsed CO2 laser. The quasi-distributed sensing array is excited by a UV LED and the normalized differential rise/decay time response measured by a smartphone is used as a measure of the temperature. The sensing spots have a volume smaller than 0.5 μL, can be separated by several millimeters to several meters and the interrogation can be simultaneous or in a sequence. The response and the sensitivity to temperature have been measured. The sensing array has been shown to measure abrupt and gradual temperature changes in space as well as time-dependent processes in the 0 °C to 100 °C range and with a measurement time of 1 s.

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
