Edge position of object image in projecting noninvariant coherent optical system

Research output: Contribution to journalConference articlepeer-review


Specific features of half-plane image formation in a coherent optical spatially noninvariant system of the 2F-2F telecentric type by the projecting objective with a limited aperture are studied (spatial filter is absent). The dependence of the light intensity on the object position at a point corresponding to the half-plane image edge is found in an analytical form using approximation of the Fresnel integrals by analytical functions. As the half-plane approaches the boundary of the field of system vision determined by the objective aperture diameter, the light intensity is demonstrated to deviate significantly, which may lead to the noticeable measurement errors.
