Abstract- In this paper، a single-mode tapered optical fiber sample، which is used for hydrogen gas sensing، is imaged using the Hilbert phase microscope method. By processing the resulting images in MATLAB software environment، after determining the phase obtained for the fiber، a three-dimensional matrix is created using the fiber phase image. By using the inverse radon transformation on the obtained matrix، the fiber refractive index profile will be accessible.
Keywords: Radon transformation, Tapered Optical fiber, Fourier slice theorem, Hilbert phase microscopy, Hydrogen Sensor.
