Estimation of the image quality correction efficiency in optical measurement systems under Scheimpflug condition

Abstract

Abstract A criterion for evaluating the image quality correction efficiency in optical systems under Scheimpflug conditions is proposed. The limits of applicability of the geometric optics approximation are clarified for the sensor tilt angle calculating. The results of a simulation optical stereoscopic system arm for three cases: normal, oblique system not under the Scheimpflug condition and oblique system under the Scheimpflug condition are presented. The quantitative estimation of the image quality correction efficiency is performed. The ranges of object distances and viewing angles, providing the maximum image quality correction without loss of accuracy due to perspective distortion are defined.
