Abstract: The present invention relates to an apparatus for acquiring three dimensional information for detecting information of wide area by making an array of photo detectors, in measuring a three dimensional image by that a light of a laser radar for three dimensional image measurement is reflected from a target object and then is incident on the photo detector through a light receiving lens. The apparatus for acquiring three dimensional information includes: a light source part for generating a light signal of fixed wavelength band; a light transmission optical lens part which is prepared on the path of the light signal and irradiates the light signal outputted from the light source in a parallel or constant angle; a light scanning part for scanning the light outputted from the light transmission optical lens to the surface of an object to measure; a light receiving optical lens part for collecting the light reflected from the surface of the object; and a light detection part for converting the light signal collected by making an array of more than one photo detector for a light receiving part to be gathered at the center, into a current signal respectively.
