The optical transfer function (OTF), as an objective measure of thequality of optical and electro-optical systems, is closely related tothe point spread function (PSF) and other derived characteristics, suchas the modulation transfer function (MTF) and the phase transferfunction (PTF). The paper focused to the use a generalized OTF, whichis primarily dedicated to the description of linear space invariantsystems (LSI), for the purpose of sampled structures of image sensors(e.g. CCD, CMOS, CID), and to implement the derived results whileutilizing the graphical user's interface (GUI) in Matlab. The modelused considers the effects of the detector photo sensitive area,sampling process, as well as other CCD specific parameters, such as thecharge transfer efficiency (CTE) or diffusion in order to derive theoverall MTF shape. The paper also includes an experimental measurementin the real system and a comparison with the results of modeling.
