SENSITIVITY ADJUSTMENT METHOD OF LASER DISTANCE MEASUREMENT APPARATUS, AND LASER DISTANCE MEASUREMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a sensitivity adjustment method of a laser distance measurement apparatus for maintaining the sensitivity in a long irradiation distance range, and reducing the sensitivity in a short irradiation distance range.;SOLUTION: The laser distance measurement apparatus 1 receives a reflection light from an object X positioned in the same direction as the irradiation direction of a laser light, and measures the distance. The laser distance measurement apparatus 1 comprises: a light emitting section 2 for irradiating the object X with the laser light; a light receiving section 3 for receiving a portion of the reflection light from the object X which does not pass through an irradiation path; and a main body section 4 for supporting the light emitting section 2 and the light receiving section 3. The light emitting section 2 and the light receiving section 3 are optically adjusted so as to form a blind spot 5 between the object X and the main body section 4 which prevents an irradiation region 2A of the light emitting section 2 and a light receiving/viewing region 3A of the light receiving section 3 from being overlapped.;COPYRIGHT: (C)2009,JPO&INPIT
