atomcloud.analysis.image_scales.all_axis_scales(lambd, xpixel_length, ypixel_length, magnification=1)[source]

Calculates the scaling values along all three axes.

Parameters:

  • lambd (float) – wavelength of the laser beam in meters

  • xpixel_length (float) – x axis length of a pixel in meters

  • ypixel_length (float) – y axis length of a pixel in meters

  • magnification (float) – magnification of the imaging setup

Returns:

scale factor for the image on the pixel axes

Return type:

tuple[dict[str, float], list[str]]

atomcloud.analysis.image_scales.convert_atom_number(atom_number, xscale, yscale, zscale)[source]

Rescale integrated values

Parameters:
