Paper Abstract

Incoherent imaging quality of optical systems will depend on the properties of the OTF. In the current paper we show an OTF-based image quality analysis, in which the properties of the OTF are represented by means of matrices, whose components depend only on the centered reduced moments of measured PSFs. Quantitative descriptors of both the geometrical characteristics and the energy distribution of the PSF (i.e. position of centers of mass, length and orientation of semi-axis, eccentricities) are determined as functions of those components. So, different aberration types can be characterized by means of the OTF properties.
