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.

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