<P>PROBLEM TO BE SOLVED: To improve light receiving efficiency to measure a distance in a comparatively wide distance detection range with relatively small structure in a distance measuring apparatus. <P>SOLUTION: A distance measuring apparatus is constituted so as to include: a light projection system which includes a two-dimensional scanner and a light projection angle magnification lens and projects a light projection beam forward; and a light receiving system which has a light receiving viewing angle equivalent to a beam scan angle of the light projection system or more, of which the first optical path regarding light reception is independent of a second optical path regarding light projection of the light projection angle magnification lens, and includes a light receiving lens arranged in the front of the light projection angle magnification lens, and in the rear of a light projection area of the light projection beam. <P>COPYRIGHT: (C)2013,JPO&INPIT |
