- finesse.utilities.maps.overlap_curvature_coefficients(x, y, z, weight_spot: float)[source]
Computes the amount of x and y curvature terms present in a map’s displacement data.
This is computed by evaluating a weighted Hermite polynomial overlap integral in an efficient manner.
- Parameters:
- x, yarray_like
1D Array of x and y describing the 2D plane of z
- zarray_like
2D optical path depth [metres]
- weight_spotfloat
Beam spot size to weight over
- Returns:
- k20, k02complex
Complex-valued overlap coefficients for the HG20 and HG02 mode
