Abstract: 조명광학계및 이를포함하는 3차원영상획득장치가개시된다. 개시된 3차원영상획득장치용조명광학계는, 3차원영상획득장치의촬영시야와일치하는조명시야를제공하기위하여소정의단면형상을갖는빔성형소자를포함할수 있다. 빔성형소자는그의단면형태에따라조명빔의형태를조절할수 있다. 따라서, 3차원영상획득장치의촬영시야내에조명빔을집중시킴으로써피사체로부터의반사광의광량을증가시켜깊이정보의정확성이향상될수 있다. 또한, 빔성형소자는광의산란이나흡수없이조명빔을균질하게하기때문에, 스펙클잡음을효율적으로억제할수 있다.

Abstract: PURPOSE: An optical system and a three-dimensional image acquisition apparatus including the optical system are provided to accurately obtain depth information about a subject. CONSTITUTION: An imaging object lens(111) forms an opening(115) in the central part through which an optical axis passes. An illuminance object lens(122) is arranged within the opening of the imaging object lens. A light source(121) provides illuminance to the illuminance objective lens. The imaging object lens and illuminance object lens share the optical axis. The optical axis of the imaging object lens accords with the optical axis of the illuminance objective lens.

Abstract: Disclosed are an imaging optical system which can be manufactured in a reduced size to make the size of a 3D image acquisition device small and the 3D image acquisition device including the same. The disclosed imaging optical system comprises a common object lens; first and second image sensors having sizes different from each other; a beam splitter providing light for the first image sensor by transmitting part of light focused by the object lens and providing light for the second image sensor by reflecting the remaining part of the light; and at least one optical element disposed between the beam splitter and the second image sensor and reducing an image which is incident on the second image sensor. The optical element includes at least one among a Fresnel lens and a diffractive optical element. [Reference numerals] (105) Display; (106) Memory; (107) Control unit

Abstract: PURPOSE: An illumination optical system and a 3D image acquisition system having the same are provided to control speckle noise generated from coherent rays without a light loss by using an integrator bar. CONSTITUTION: An illumination optical system(230) comprises a light source(131), a beam forming device(133), and a lens device(134). The beam forming device homogenizes lights emitted from the light source and changes a beam sectional shape of the lights. The lens device focuses the lights have passed through a light projecting surface of the beam forming device on a subject. The beam sectional shape of the lights have passed through a light projecting surface of the beam forming device is the same with the beam sectional shape of the beam forming device. The beam sectional shape of the beam forming device accords with a photographing view field of a 3D image acquisition system.
