WebThe modulation transfer function (MTF) is calculated by Fourier transforming the PSF (of green light only) and taking the absolute value. The MTF is plotted below. We see that the MTF is eventually limited by the 4 micron spacing between the green pixels, meaning that the maximum resolution is 125 cycles per mm (0.5/4 micron). WebA theoretical modulation transfer function (MTF) curve can be generated from the optical prescription of any lens. Although this can be helpful, it does not indicate the actual, real …
