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. [--]
