Point spread function remote sensing
WebThe line-spread function is directly proportional to the vertical integration of the point-spread image. The optical-transfer function (OTF) is defined as the Fourier transform of the point-spread function and is thus generally a two … WebMay 19, 2024 · The beam spread function (BSF) is then defined as the detected irradiance normalized by the emitted power: B S F ( r, 𝜃) ≡ E ( r, 𝜃) P W m − 2 n m − 1 W n m − 1 = m − 2. (1) Recall that the Volume Scattering Function (VSF) describes a single scattering event. Two such scatterings are shown for the green arrows in Fig. 1 .
