Design of a model of a sensor based on the Shape from focus method is presented. The model uses polychromatic point spread functions of a generalized aperture function of lens and their convolution with an ideal image. The model approaches the reality and allows one to employ parameters of real components of the corresponding sensor, e.g. a spectrum of a light source, a dispersion function of a real imaging optical system and spectral sensitivity of a real light sensitive sensor. The model enables to study accuracy and reliability of the determination of the object's surface topography by means of the Shape from focus method.
