Web20 ian. 2009 · Expressions for the point spread function (PSF) and the modulation transfer function (MTF) of the Golay 3 MMT are deduced, and the characteristics of the PSF and MTF are explored based on the derived equations and Matlab simulation. Designs for two Cassegrain telescopes with the Golay3 configuration have been developed. WebThe objective being to design a system that creates a “good image”. However, there are different metrics to evaluate what is a “good image”. Most of the time, a customer won’t express their image quality requirements in terms such as MTF or ray aberration plots. However, they know what they want the optical system to do.

WebThe PSF and especially the MTF are important function to describe a telescopes quality. The PSF is in fact only a slice of the values that appear on the X-axis (Y=0) and on the Y-axis (X=0) of the generated star-image. The MTF is far more important since it shows the effects of aberrations in terms of losses at different resolutions. WebThe incoherent diffraction MTF plays an increasingly important role in the range performance of imaging systems as the wavelength increases and the optical aperture decreases. Accordingly, all NVESD imager models have equations that describe the incoherent diffraction MTF of a circular entrance pupil.
