I need to measure the light intensity profile of a double-slit interference pattern with high precision.

1. Is it possible to get reliable quantitative intensity data using ImageJ?
2. How should I process the image to get the most accurate line profile

I am currently working on my extended essay focusing on the double slit experiment and the wave nature of light. While the standard fraunhofer provides a general framework, ı want to derive a custom relationship between the light intensity and the slit width to compare the datas from another perspective. By which formulas ı can achieve this goal?
