A light projector and method of aligning the light projector is provided. A light projector steers an outgoing beam of light onto an object, passing light returned from the object through a focusing lens onto an optical detector. The light projector may generate a light pattern or template by rapidly moving the outgoing beam of light along a path on a surface. To place the light pattern/template in a desired location, the light projector may be aligned with an electronic model.

Laser projector system

A laser projector steers a pulsed laser beam to form a pattern of stationary dots on an object, the pulsed laser beam having a periodicity determined based at least in part on a maximum allowable spacing of the dots and on a maximum angular velocity at which the beam can be steered, wherein a pulse width of the laser beam and a pulse peak power of the laser beam are based at least in part on the determined periodicity and on laser safety requirements.

Laser projector

A laser projector steers an outgoing beam of light onto an object, passing light returned from the object through a focusing lens onto an aperture rigidly coupled to an optical detector.

Background light suppression for a laser projector

A laser projection system is provided. The laser projection system includes at least one laser projector having a laser source and a laser detector. The system includes processors for executing computer instructions, the processors are coupled to the laser projector, the computer readable instructions include determining the component is stationary based on the emitting of a first laser light towards a reference target on the component and receiving a portion of the first laser light by the laser detector. In response to the determining the component is stationary: determining a transformation for mapping a first coordinate system of the laser projector to a second coordinate system of the component and forming a visual pattern on the component. The computer instructions further include determining that the component is in motion based on receiving a portion of the first laser light by the laser detector and removing the visual pattern.

3D laser projection, scanning and object tracking

Techniques are disclosed for tracking the position of moving parts and assemblies using 3D laser projection, and projecting templates and other information onto the parts and assemblies based on position. The projected template may then be used, for example, to assist in fabrication of an assembly by indicating where to put a next component or layer, or to assist in post-fabrication inspection of an assembly by indicating where the various components or layers should have been placed. Reference targets can be used as fiducial points for aligning a laser projector with the work piece in question. When the work piece rotates or is otherwise moved to a next manufacturing or inspection position, the relative position of the laser projector and the work piece is updated by bucking-in to the reference targets. The laser projector can then project patterns or other information onto the work piece at the appropriate locations.

A laser projection system is disclosed. The system includes a laser projector that projects a light beam to the surface of an object and scans that projected light beam over at least a portion of the surface, wherein a portion of the projected beam is diffusely reflected from the surface back to the system. The system further includes an optical signal detector that receives the feedback light beam and converts it to an image signal, a light suppression means for suppressing unwanted light from entering the optical signal detector, and a computer for producing a measurement of the distance from the projector to the object surface, and controlling the system to buck the laser projector into a coordinate system of the object using three or more features on the object, wherein at least one of the three or more features serves as a targetless fiducial point.

Laser radar projection with object feature detection and ranging

A 3D pulsed laser projection system scans an object to produce a dense 3D point cloud and projects a laser light beam onto an object as a glowing template. A high-sensitivity optical feedback system receives and detects a feedback beam of the output beam light diffusely reflected from the object. The feedback light and projected beam share the same beam path between steering mirrors and the object. A light suppression component controls stray scattered light, including ambient light, from being detected. A time-of-flight measurement subsystem provides a distance-to-object measurement for projected pulses. An acousto-optical modulator, variable gain detected signal amplification and variable photo-detector power together produce a dynamic range for detected reflected feedback signals of at least 100,000, and up to 500,000. Optical fiber cables spatially filter scattered light and isolate the photo-detectors thermally. The laser is preferably pulsed at least 50 kHz, with sampling of the projected and feedback reflected optical pulse signals at a sampling rate of up to 10 gigasamples per second.

A laser projection system scans an output laser light beam onto an object to detect features. A high-sensitivity optical feedback system receives and detects a feedback beam of the output beam light diffusely reflected from the object. The feedback light and projected output beam share the same beam path between beam-steering mirrors of the projector and the object. The laser projection system has light suppression components to control stray scattered light, including ambient light, from being detected. A computer of the laser projection system calculates fiducial points on the object from detected features to align the projection system with the object without using targets. This feature detection is used in a process to guide assembly and fabrication on or to the object, and to verify the accurate placement of parts and fabrication steps in place after they are assembled or processed. In one form, the detected feature is a light spot on the object produced by a second light source.
