An illumination optical system of a 3-dimensional (3D) image acquisition apparatus and a 3D image acquisition apparatus including the illumination optical system. The illumination optical system of a 3D image acquisition apparatus includes a beam shaping element which outputs light having a predetermined cross-sectional shape which is proportional to a field of view of the 3D image acquisition apparatus. The beam shaping element may adjust a shape of illumination light according to its cross-sectional shape. The beam shaping element may uniformly homogenize the illumination light without causing light scattering or absorption.

An imaging optical system and a three-dimensional (3D) image acquisition apparatus which includes the imaging optical system are provided. The imaging optical system includes an object lens configured to transmit light; first and second image sensors having different sizes from each other; a beamsplitter on which the light transmitted by the object lens is incident, the beamsplitter being configured to split the light incident thereon into light of a first wavelength band and light of a second wavelength band, and to direct the light of the first wavelength band to the first image sensor and the light of the second wavelength band to the second image sensor; and at least one optical element, disposed between the beamsplitter and the second image sensor, configured to reduce an image that is incident on the second image sensor, the optical element including at least one of a Fresnel lens and a diffractive optical element.

Imaging optical system for 3D image acquisition apparatus, and 3D image acquisition apparatus including the imaging optical system

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.
