Abstract :
A method to extract quantitative phase data from differential interference contrast (DIC) microscopic images is presented. This method in conjunction with the inverse Abel transform is used to obtain an accurate refractive index profile of a calibrated multi-step optical fibre (National Physical Laboratory). Results of the refractive index profile are compared with that determined by the calibration process.
