Abstract
Fiber specklegram sensors utilize the unique interference patterns produced by coherent light
interacting with the structure of optical fibers to detect changes in environmental conditions.
These sensors are highly sensitive to variations in parameters such as refractive index, pressure,
temperature, and strain, making them suitable for a wide range of applications. Their capacity
to deliver real-time, precise information makes them useful in industries including industrial
monitoring, environmental sensing, biological diagnostics, and structural health monitoring.
In this thesis, we present the development and application of advanced software for analyzing
fiber optic speckle patterns using polymer optical fibers. Our goal was to enhance the capability
of speckle sensing specifically for liquid and pressure sensing applications. The software,
developed in Python, integrates various image processing algorithms to detect and analyze
changes in the specklegram under different conditions. Key features include real-time image
acquisition, video capture, live imaging filters, and a cropping tool. We also conduct
experiments to evaluate the software's performance in liquid and pressure sensing,
demonstrating its effectiveness and potential for broad applications.
