I attempted to measure the intensity of the light. But I also planned to measure refractive index. We used a laser transmitter and receiver. I use Autonics FD62010, stripped it half (only on 1 side) with a cutter manually and then do electrospinning on the stripped area. We attempt to create concentration gas sensor.
Dear friend Tristofani Agasta
To measure the refractive index of an optical fiber added with electrospun PVA-rGO, you can use a technique called the prism coupling method. Here are the steps to follow:
Note: In the prism coupling method, the refractive index of the coating on the fiber is determined by measuring the angle at which light is coupled from the prism into the fiber. The intensity of the coupled light depends on the refractive index of the coating and the prism. By measuring the output angle and intensity, you can calculate the refractive index of the coating.
This method is commonly used to measure the refractive index of thin films or coatings on optical fibers. However, it may not be suitable for measuring the refractive index of a coating in a gas sensor application, as the presence of gas may affect the measurement. In such cases, you may need to use a different method or modify the prism coupling method to account for the presence of gas.
