pybsm.otf.functional.detector_OTF

pybsm.otf.functional.detector_OTF(*, u: ndarray, v: ndarray, w_x: float, w_y: float, f: float) → ndarray

A simplified version of IBSM Equation 3-36.

Blur due to the spatial integrating effects of the detector size. See detector_OTF_with_aggregation if detector aggregation is desired (new for version 1).

Parameters:

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

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

• w_x – the 1/e blur spot radii in the x direction

• w_y – the 1/e blur spot radii in the y direction

• f – focal length (m)

Returns:

H:

detector OTF. WARNING: output can be NaN if f is 0
