Derivation of imaging formula of filmy lens from concave lens
Abstract：By means of Fermat principle, the imaging formula of filmy lens is deduced from concave lens,and the optical path can be replaced by a simple and equivalent way when a virtual image is present. The imaging of spherical reflex and spherical refraction can both be regarded as a special case in the imaging of filmy lens. As a result, the deduction and analysis are of practical value and universality concerning the imaging formula of filmy lens.
