WebDiffraction Modulation Transfer Function. Diffraction MTF is a wave-optics calculation for which the only variables (for a given aperture shape) are the aperture diameter D, wavelength λ, and focal length f. The MTF diffraction is the upper limit to the system’s performance; the effects of optical aberrations are assumed to be negligible. WebIn optics, various autocorrelation functions can be experimentally realized. The field autocorrelation may be used to calculate the spectrum of a source of light, while the intensity autocorrelation and the interferometric autocorrelation are commonly used to estimate the duration of ultrashort pulses produced by modelocked lasers. WebManuscript Accepted: July 12, 1990 Published: October 1, 1990 PDF Article Abstract We show that induced-grating/four-wave-mixing ultrashort-pulse autocorrelation techniques that use slowly responding media offer the same phase information as interferometric second-harmonic generation. tourist attractions near cleveland ohio
