pybsm.otf.functional.detector_OTF_with_aggregation(*, u: ndarray, v: ndarray, w_x: float, w_y: float, p_x: float, p_y: float, f: float, n: int = 1) → ndarray

Blur due to the spatial integrating effects of the detector size and aggregation.

Contributed by Matt Howard. Derivation verified by Ken Barnard. Note: this function is particularly important for aggregating detectors with less than 100% fill factor (e.g. p_x > w_x).

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

• p_x – detector pitch in the x direction (m)

• p_y – detector pitch in the y direction (m)

• f – focal length (m)

• n – number of pixels to aggregate

Returns:
