Abstract

More and more applications need stereoscopic imaging to analyze the characteristic of things, so three-dimensional information is needed to visualize and analyze. The stereoscopic imaging can be obtained by single camera or two cameras. There are several approaches for creating stereo images with a single camera. One of the simplest and most frequently used has been to place an optical adapter in front of the existing lens, and two images are formed by two beams through one camera lens. Biprism can be used as stereo adapter. As light go through the biprism, an angle change occurs due to the prism, the light refracted at the two surfaces, angle of the prism α with also reflection index n determine the angle change δ of the light. And δ is the maximum field of view. Bigger angle of biprism can obtain bigger range of stereoscopic imaging, however, the larger of the angle of biprism, the larger of lateral color aberration the biprism caused, which can affect the resolution of the stereoscopic imaging. This paper also analyzes the nonlinear magnification and color aberration of the biprism stereo adapter.
