Abstract

In this paper, we propose a new design of an imaging optical system combining the advantages of stereoscopy and spectroscopy principles. The quality of spectral stereoscopic image is the key factor influencing the accuracy of threedimensional (3D) measurements and shape reconstruction. The main advantages of acousto-optical tunable filters (AOTF) in combination with stereoscopic imager are shown. We developed a new scheme of an imaging AOTF-based stereospectrometer in order to raise accuracy of 3D-measurements. According to numerical simulation, the scheme has improved image quality compared with existing ones.
