Improvement to M^2 Measurement #46

Open sunjerry019 opened 2 years ago

sunjerry019 commented 2 years ago

Currently, the setup:

  1. Finds the center
  2. Finds the Z_R
  3. Measures the M^2

The M^2 measurement may be sped up by

  1. Taking rough measurements of the beam caustic
  2. Doing a fit to obtain rough Z_R and center measurements
  3. Taking a few more measurements within the +/-Z_R range.
  4. Doing a refit

This reduces the total number of measurement points significantly.
