The LSF is shown in Figure 2 as well, with reference to the right vertical axis. Once the LSF is known, the magnitude of the FFT of this LSF is calculated. Nettet8. okt. 2024 · The line spread function (LSF) is derived by averaging the pixel intensities, the point spread function (PSF) values, surrounding the wire. The x and y-axis PSF values are averaged and symmetrized, and then both directions are averaged to create the LSF plot.

NettetFor the first definition of the MTF you should notice that the line-spread-function is the gradient of the edge-spread-function perpendicular to the edge. Since your edge is rotated relative to the detector you have to correct for that (or do some additional work to squeeze out sub-pixel resolution for the ESF).

Nettet2. okt. 2014 · The Line Spread Function (LSF) is computed as the differential of the measured Edge Spread Function (ESF).
