expanded foucault messerkantenverfahren to quantitative study of an optical abbildungsvorrichtung

摘要

The historical Foucault knife-edge test enables one to qualitatively ascertain an optical imaging device's characteristics, for example, whether or not it is a source of optical aberrations. The novel method of the present invention, in sharp contrast, complements the historical Foucault knife-edge test, by expanding the test so as to develop a quantitative interpretation of the imaging device's characteristics.
