python project that profiles beams

Overview

The goal of this project is to process images of laser beams to measure their size and position. The code uses a 1D Gaussian function to fit the data and measure beam properties. Tracking the position of the beam over time helps measure pointing stability.

pre condition

• input.txt is in the same directory with beam_profiler.py
• the first line in input.txt has the abslute path to the directory with the tif files
• the second line in input.txt has the sensor size in millimeters
• the directory with the tif files has at least one tif file

output

• Beams average size x in micrometers
• Pointing stability in axis x in micrometers
• Pointing stability in axis y in micrometers
• Pointing stability in axis r in micrometers
• Beams average x postion in pixels
• Beams average y postion in pixels
• Pixel size in micrometers
• Name of the directory of the images
