Abstract: The present disclosure relates to an apparatus for obtaining 3D information using a photodetector array. The apparatus for obtaining 3D information includes: a light source unit configured to generate an optical signal of a predetermined wavelength band; a light transmission optical lens unit provided on a path of the optical signal and configured to emit the optical signal output from the light source unit in parallel or at a predetermined angle; an optical scanning unit configured to scan the light output from the light transmission optical lens unit to a surface of an object to be measured; a light reception optical lens unit configured to collect the light reflected from the surface of the object; and a photodetection unit configured to convert collected optical signals into respective electrical signals by arraying one or more photodetectors such that light reception portions thereof are collected at a center.
