pybsm.otf.functional.jitter_OTF(*, u: ndarray, v: ndarray, s_x: float, s_y: float) ndarray

IBSM Equation 3-28. Blur due to random line-of-sight motion that occurs at high.

frequency, i.e. many small random changes in line-of-sight during a single integration time. Note that there is an error in Equation 3-28 - pi should be squared in the exponent.

Parameters:
  • u – angular spatial frequency coordinates (rad^-1)

  • v – angular spatial frequency coordinates (rad^-1)

  • s_x – Root-mean-squared jitter amplitudes in the x direction respectively. (rad)

  • s_y – Root-mean-squared jitter amplitudes in the y direction respectively. (rad)

Returns:

H:

OTF at spatial frequency (u,v) (unitless)
