Abstract

The performance of a photographic film as a recording medium can be characterized, in part, by its modulation transfer function (MTF). The MTF is giving us the dependence of image contrast on the structure of the imaged object which is expressed by its spatial frequencies. For the measurement of the MTF we can generate test signals either by an optical projection of a test chart, or by direct creation of signals on a film. In this paper we demonstrate a new method for the MTF measurement, based on a principle of forming a sine grating test directly on the film by means of a fiber-optic interferometer.
