pybsm.otf.functional.dark_current_from_density

pybsm.otf.functional.dark_current_from_density(*, jd: float, w_x: float, w_y: float) → float

The dark current part of Equation 3-42.

Use this function to calculate the total number of electrons generated from dark current during an integration time given a dark current density. It is useful to separate this out from 3-42 for noise source analysis purposes and because sometimes dark current is defined in another way.

Parameters:

• jd – dark current density (A/m^2)

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

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

Returns:

jde :

dark current electron rate (e-/s); for TDI systems, just multiply the result by the number of TDI stages
