Abstract

The present research exposes a novel methodology to manufacture fiber optic sensors following the etching process by Hydrofluoric Acid deposition through a real-time monitoring diameter measurement by computer vision. This is based on virtual instrumentation developed with the National Instruments technology and a conventional digital microscope. Here, the system has been tested proving its feasibility by the SMS structure diameter reduction from its original diameter of 125 μ until approximately 42.5 μm. The results obtained have allowed us to demonstrate a stable state behavior of the developed system during the etching process through diameter measurement at three different structure sections. Therefore, this proposal will contribute to the etched fiber optic sensor development that requires reaching an enhanced sensitivity. Finally, to demonstrate the previously mentioned SMS without chemical corrosion, and the etched manufactured SMS, both have been applied as glucose concentration sensors.

摘要

本研究揭示了一种新颖的制造光纤传感器的方法，该方法通过计算机视觉实时监测直径测量，采用氢氟酸沉积进行蚀刻处理。这是基于虚拟仪器仪表开发的，采用了 National Instruments 技术和传统的数字显微镜。在这里，该系统已经过测试，通过 SMS 结构直径从原始直径 125μm 减小到约 42.5μm，证明了其可行性。所获得的结果使我们能够通过在三个不同结构部分进行直径测量，证明了在蚀刻过程中开发的系统的稳定状态行为。因此，本提案将有助于开发需要提高灵敏度的蚀刻光纤传感器。最后，为了演示之前提到的无化学腐蚀的 SMS 和制造的蚀刻 SMS，我们都将其用作葡萄糖浓度传感器。
