pybsm.otf.functional.image_domain_defocus_radii(*, D: float, dz: float, f: float) float

IBSM Equation 3-27. Axial defocus blur spot radii in the image domain.

Parameters:
  • D – effective aperture diameter (m)

  • dz – axial defocus in the image domain (m)

  • f – focal length (m)

Returns:

w :

the 1/e blur spot radii (rad) in one direction

Raises:
ZeroDivisionError:

if slant_range is 0
