Photometric techniques are one of the three-dimensional image reconstruction technologies. It is used in various fields, especially surface analysis because it focuses on extracting information such as texture and color. perform 3D using light sources a camera. If object has specular reflection properties, then an error may occur reconstructed data according to noise intensity acquired images. For solution these problems, optical system configurated by dome coaxial light, non-uniformity area defined derived mathematical formulas this paper. In order verify validity formulas, simulations experiments have been conducted. As result, was confirmed that proposed design method could be new technique for uniform system.
