    Abstract: A laser scanner includes a light emitter that generates a modulated light beam for measuring distance and red, blue, and green lights for capturing colors. The beam is collimated and directed to an object point with a steering mirror. Reflected light from the object point is directed by the steering mirror onto scanner optics. The reflected light is directed to an optical receiver that sends the first light in a first path and the second, third and fourth lights in a second path to a color receiver. The first light is demodulated to determine distance to the target. The second, third, and fourth lights are separated and measured to determine three color values. The color values are combined with the measured distance value to determine a color 3D coordinate for the object point.

    Abstract: A 3D measurement device sends a beam of light to a point on an object, receives the reflected light, and determines a distance and two angles to the point, one of the angles measured by an angular encoder, which includes a disk having incremental marks and an index mark. Light from the 3D device is rotated to reflect light from a reference reflector to produce a first synchronization signal. A first difference angle is determined based on counts of the incremental marks and on the first synchronization signal. Light from the 3D device is rotated to reflect light from the reference reflector to produce a second synchronization signal. A second difference angle is determined based on counts of the incremental marks and on the second synchronization signal. The reference correction value of the index mark is determined based on the first and second difference angles.

    Abstract: A laser scanner and method of operation to determine the consistency of a registration is provided. The method includes generating with the laser scanner at least a first scan of the scene with first measuring points. The laser scanner generates at least one second scan of the scene with second measuring points. At least one measured distance is determined from at least one of the second measuring points to the center of the second scan. The second scan is provisionally registered subjected to a consistency check. The consistency check is performed. At least one virtual distance is determined from at least one of the first measuring points to the center of the second scan. The consistency check is based at least in part on comparing the at least one virtual distance with the at least one measured distance.
