Investigation of the influence lens axis inclination to the camera sensor axis on depth of field

Abstract

In the report are represented the results of experimental investigation of the influence photographic lens axis inclination to the camera sensor axis for the optical system with Scheimpflug adapter, for an object at a finite distance. A method of determining the depth of field by the image of the background pattern for optical systems in which the plane of the digital camera matrix is not perpendicular to the optical axis of the lens is proposed. Described facility for the background pattern image capturing, the rotation of the lens which is carried out using the Scheimpflug adapter. The distributions of the mean square deviation across the background pattern image for different mutual positions of the axes of the camera matrix and lens are obtained.
