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.
