Web20 ian. 2024 · The MTF of the optical system in each field of view is greater than 0.3 at 100 lp/mm, and RMS is controlled below 5 μm, indicating that the imaging quality is good. The zoom optical system only uses spherical lenses instead of aspheric lenses and diffractive optical elements for design. The results of the tolerance analysis show that the ... Weboptical performance is the modulation transfer function (MTF). In a finite element program, the calculation of random response provides PSD response functions for LoS errors and net RMS results. WebThe MTF is a part of the complex function describing this process, called Optical transfer function (OTF). While OTF is limited to the effect of system PSF on imaging this single form of object - a sinusoidal intensity distribution - it is accepted as a performance indicator for imaging in general.
