WebMar 31, 2024 · Modulation Transfer Function (MTF) is an important method of describing the performance of an optical system. MTF describes the imaging of the system, but an important system parameter is usually neglected: the resolution of the detector. 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). crystal body deodorant towelettes lavendar
