  • Optical system having integrated illumination and imaging optical systems, and 3D image acquisition apparatus including the optical system
    Patent number: 9170471
    Abstract: An optical system including integrated illumination and imaging optical systems, and a 3-dimensional (3D) image acquisition apparatus including the optical system. In the optical system of the 3D image acquisition apparatus, the illumination optical system and the imaging optical system are integrated to have a coaxial optical path. Accordingly, there is no parallax between the illumination optical system and the imaging optical system, so that depth information about an object acquired using illumination light may reflect actual distances between the object and the 3D image acquisition apparatus. Consequently, the depth information about the object may be more precise. The zero parallax between the illumination optical system and the imaging optical system may improve utilization efficiency of the illumination light. As a result, a greater amount of light may be incident on the 3D image acquisition apparatus, which ensures to acquire further precise depth information about the object.
