WebThe modulation transfer function (MTF) curve is an information-dense metric that reflects how a lens reproduces contrast as a function of spatial frequency (resolution). These curves offer a composite view of how optical aberrations affect performance at a set of fundamental parameters set by application need. WebSelf-phase modulation (SPM) is a nonlinear optical effect of light–matter interaction. An ultrashort pulse of light, when travelling in a medium, will induce a varying refractive index of the medium due to the optical Kerr effect. This variation in refractive index will produce a phase shift in the pulse, leading to a change of the pulse's frequency spectrum.
