WebA roadmap for Fourier optics illustrating two paths for computing the retinal image of an object when the point spread function of the eye (PSF), or equivalently, the optical transfer … WebOct 1, 2005 · Ed Grainger developed the SQF at Eastman Kodak in the 1970s. Grainger wanted a single metric that would correlate with perceived image quality. In his definition, SQF is constructed by suitably weighting the MTF values between 0.5 and 2.0 lines/mm. In somewhat simplified terms, SQF is just the average MTF from 0.5 to 2 cycles per mm.
