US 6,784,985 B2 · Three-dimensional laser beam detection device

Abstract

A three-dimensional laser beam detection device. The three-dimensional laser beam detection device has a portion fixed to a laser source such as an optical head, an adjusting device provided on the fixed portion, and a laser beam detection portion coupled to the adjusting device. The adjusting device has a first table movably coupled to the fixed portion in a first direction, and a first adjusting portion coupled to the first table for moving the first table relatively to the fixed portion in the first direction. The first adjusting portion is formed within the adjusting device. The laser beam detection portion has a detector to detect the laser beam radiating from the laser source. The fixed portion has a fixed relative position to the laser source, and the detector is adjustable in relation to the laser source by performing adjustment with the adjusting device.
