WebIn the scanning method for OTF measurement either a sinusoidal grating is used as a test object and the image of the grating is scanned by a slit or point detector, or, equi- valently, a slit or point source is used as a test object and the image of the slit is scanned by a sinusoidal grating. WebOTF = psf2otf (PSF) computes the fast Fourier transform (FFT) of the point-spread function ( PSF) array and creates the optical transfer function array, OTF, that is not influenced by the PSF off-centering. OTF = psf2otf (PSF,sz) specifies the size, sz, of the optical transfer function. Examples collapse all Convert PSF to OTF
