20110001958 | LASER-BASED COORDINATE MEASURING DEVICE AND LASER-BASED METHOD FOR MEASURING COORDINATES - A laser based coordinate measuring device measures a position of a remote target. The laser based coordinate measuring device includes a stationary portion, a rotatable portion, and at least a first optical fiber. The stationary portion has at least a first laser radiation source and at least a first optical detector, and the rotatable portion is rotatable with respect to the stationary portion. The first optical fiber system, which optically interconnects the first laser radiation source and the first optical detector with an emission end of the first optical fiber system, has the emission end disposed on the rotatable portion. The emission end emits laser radiation to the remote target and receives laser radiation reflected from the remote target with the emission direction of the laser radiation being controlled according to the rotation of the rotatable portion. | 01-06-2011 |

20120327390 | METHODS FOR USING A LOCATOR CAMERA IN A LASER TRACKER - A method of steering a laser beam from an instrument toward a point on a retroreflector, including: intercepting with the retroreflector a cone of light from the instrument; obtaining a first image of retroreflected light on a photosensitive array and transmitting an electrical data signal in response; determining a position on the photosensitive array of the first image; calculating first and second angular increments to steer the laser beam to the point; rotating the first and second motors to intercept with the position detector the retroreflected laser beam and to place the laser beam at a preferred location on the position detector; measuring fifth and sixth angles with first and second angle transducers; measuring a distance with a distance meter; and determining three-dimensional coordinates of the point based at least in part on the fifth angle, the sixth angle, and the distance. | 12-27-2012 |
20150211851 | LASER BASED COORDINATE MEASURING DEVICE AND LASER BASED METHOD FOR MEASURING COORDINATES - A method for measuring a distance includes modulating the light beam at a first frequency, receiving a second beam by the optical detector to produce a first electrical signal having the first frequency and a first phase; modulating the light beam at a second frequency different than the first frequency; receiving the second beam by the optical detector to produce a second electrical signal having the second frequency and a second. After these steps, the retroreflector is moved while modulating the light beam continuously at the second frequency; and a first distance to the retroreflector is determined based at least in part on a the first and second frequencies and phases. | 07-30-2015 |
