Usage of PSF & MTF Detector

Point spread function (PSF) and modulation transfer function (MTF) are important optical quantities to evaluate the quality of an imaging system. Two-dimensional (2D) PSF and MTF are highly required for optical systems of high NA or non-symmetry. In VirtualLab Fusion, PSF and MTF (both 1D and 2D evaluations) for an imaging system can be calculated fast and accurately by using the PSF & MTF detector.
