This paper describes an extension of the MTF concept to solid state imagers optically coupled to fiber-optic faceplates. An analysis of the image formation is presented and the limitations of the conventional MTF concept are discussed. An MTF simulation is performed for a fiber-optic faceplate with a 5μm fiber diameter, a line-scan CCD image sensor with a 13μm pixel pitch and the same sensor optically coupled to the faceplate. The MTFs of the sensor with and without the faceplate, measured using a knife-edge technique, are compared to the simulated MTFs and found to be in good agreement provided that imperfect Extra Mural Absorption (EMA) is included in the analysis.
