20120062867 | LASER DISTANCE MEASUREMENT APPARATUS - A laser-radar distance measurement apparatus for measuring the distance between two arbitrary points on a measurement target in a non-contact fashion has a light emitter, a light receiver, a scanner, and a calculation controller. The light emitter emits laser light. The scanner deflects the laser light from the light emitter to irradiate with the laser light the two arbitrary points on the measurement target one after the other, and performs one-dimensional scanning along a straight line including the two arbitrary points. The light receiver receives the laser light reflected from the two arbitrary points to output signals respectively. The calculation controller calculates the distance between the two arbitrary points based on the signals output from the light receiver and operation information on the scanner. | 03-15-2012 |
