pwspy.utility.DConversion.calcDSize(raw_rms, noise, NAi)[source]

The system_correction argument from the original MATLAB function has been excluded. We assume that any RMS values being provided to this function have already been properly corrected for hardware defects.

  • raw_rms (ndarray) – An array of RMS values you wish to convert.

  • noise (float) – A positive value indicating the background noise in the system in terms of RMS (E.G. the RMS of a measurement of clean glass). On the Backman lab “STORM” system this has been previously found to be 0.012. For the “LCPWS1” system it has been found to be 0.009.

  • NAi (float) – The illumination numerical aperture (NA) of the objective.
