A three-dimensional (3D) scanner includes a light source, an optical detector, a reference reflector, and a 3D aperture structure having side walls and an aperture, the aperture sized to pass a first portion of the light reflected by the reference reflector, the side walls sized to block a second portion of the light reflected by the reference reflector. The 3D scanner further includes a tilted optical bandpass filter to block ambient background light without creating cavity reflections that might cause errors in measured distance.

A device and method for projecting a light pattern is provided. The device includes a processor system and a housing. The housing is rotatable about a first axis. A measurement device is operably coupled to the housing that measures a distance to a surface in an environment. A light projector is operably coupled to the housing, the light projector having a light source and a pair of movable mirrors, the light source positioned to emit light onto the pair of movable mirrors. Wherein the processor system is responsive to computer instructions for: determining 3D coordinates of points on the surface with the 3D measurement device; selecting a pattern; adjusting the pattern based at least in part on the 3D coordinates; and causing the light projector to emit a beam of light and moving the pair of mirrors to generate the adjusted pattern on the surface.

A device and method for projecting a light pattern is provided. The device includes a processor system and a housing. A three-dimensional (3D) measurement device is operably coupled to the housing that measures a distance to a surface in an environment. A laser projector is operably coupled to the housing, the laser projector having a light source and a pair of movable mirrors, the light source positioned to emit light onto the pair of movable mirrors. Wherein the processor system is responsive to non-transitory executable computer instructions for: determining 3D coordinates of points on the surface with the 3D measurement device; selecting a pattern; causing the laser projector to emit a beam of light and moving the pair of mirrors to generate the pattern on the surface; and adjusting the pattern based at least in part on the 3D coordinates.

A three-dimensional (3D) measuring device and a method of operating is provided. The 3D measuring device includes a housing and a processor system including at least one of a 3D scanner controller. A 3D scanner is disposed within the housing and operably coupled to the processor system, the scanner having a light source, a beam steering unit, a first angle measuring device, a second angle measuring device, and a light receiver. The scanner cooperates with the processor system to determine 3D coordinates of an object point. A laser projector includes a second light source and a movable mirror system, the second light source positioned to emit light onto the movable mirror system. The processor system causes the light source to emit light and the mirror to move to generate a pattern on a surface in the environment based at least in part on the 3D coordinates.
