- pybsm.otf.functional.object_domain_defocus_radii(*, D: float, R: float, R0: float) float
IBSM Equation 3-26. Axial defocus blur spot radii in the object domain.
- Parameters:
D – effective aperture diameter (m)
R – object range (m)
R0 – range at which the focus is set (m)
- Returns:
- w :
the 1/e blur spot radii (rad) in one direction
- Raises:
- ZeroDivisionError:
if R or R0 is 0
