pybsm.otf.functional.diffusion_OTF(*, u: ndarray, v: ndarray, alpha: ndarray, ald: ndarray, al0: ndarray, f: float) → ndarray

IBSM Equation 3-40. Blur due to the effects of minority carrier diffusion in a CCD sensor.

Included for completeness but this isn’t a good description of modern detector structures.

Parameters:

u – spatial frequency coordinates (rad^-1)
v – spatial frequency coordinates (rad^-1)
alpha – carrier spectral diffusion coefficient (m^-1); note that IBSM Table 3-4 contains alpha values as a function of wavelength for silicon
ald – depletion layer width (m)
al0 – diffusion length (m)
f – focal length (m)

Returns:
