<P>PROBLEM TO BE SOLVED: To provide an optical distance measuring equipment for measuring a distance to each of objects 15 and 16 even when there exists a plurality of objects 15 and 16 in a projecting direction from a light emitting element 11. <P>SOLUTION: The optical distance measuring equipment is provided with: a light emitting element 11; a light collecting part 13 for projection; a condensing part 14 for light reception; and a light receiving element 12. The light receiving element 12 has a light receiving face 12a for receiving optical spots Ls1 and Ls2 condensed by the condensing part 14 for light reception. A plurality of light receiving elements are one-dimensionally or two-dimensionally arrayed in a row on a light receiving face 12a. When the optical spots Ls1 and Ls2 are made incident to the light receiving face 12a, positions x1 and x2 in the light receiving face 12a of the optical spot are searched for each of the optical spots Ls1 and Ls2 based on a signal to be output by each of the plurality of light receiving elements. A distance from the light emitting element 11 to objects 15 and 16 corresponding to each optical spot is calculated by a triangular distance measurement system according to the positions x1 and x2 within the light receiving face of each optical spot. <P>COPYRIGHT: (C)2012,JPO&INPIT |
