sinc#
- abtem.integrals.sinc(gpts, sampling, device='cpu')[source]#
Returns an array representing a 2D sinc function centered at [0, 0]. The result is used to compensate for the finite size of single pixels used for representing delta functions.
- Parameters:
gpts (two int) – Number of grid points in the first and second dimension to evaluate the sinc over.
sampling (two float) – Size of the pixels of the grid determining the scale of the sinc.
device (str) – The array is created on this device (‘cpu’ or ‘gpu’).
- Return type:
ndarray
