Lasertrace

Lasertrace is a term used to describe a laser-based tracing system or technique that projects a controllable laser path to guide alignment, measurement, or marking tasks. It is not a single standardized technology, but rather a category that can include live-scanning laser lines, projected beacons, or pattern traces generated by modulating a laser beam with scanning mirrors, acousto-optic deflectors, or MEMS devices.

Typical lasertrace systems combine a laser source, a beam-scanning or projection unit, optical delivery optics, and sensing and control software. The scanner or projector drives the beam to follow a predefined trajectory, while sensors—such as position cameras, photodetectors, or retroreflective targets—capture the traced path or its reflections. The software compares measured data to reference geometry, computes deviations, and can adjust machinery or produce measurement results and 3D models.

Output formats may include a projected line on a workpiece for alignment, a set of marked points, or a collected dataset used for quality control or metrology. In many configurations the system operates in real time to guide tools, fixtures, or robots.

Applications include industrial manufacturing and assembly for alignment and calibration; dimensional metrology and reverse engineering; construction and surveying for layout; and research laboratories for experiments requiring controlled, non-contact tracing of paths.

Because lasers can damage eyes and skin, lasertrace devices are subject to appropriate laser safety classifications and regulatory standards. Proper enclosure, interlocks, eye protection, and user training are typical requirements.

Although widely used as a descriptive term, lasertrace has not been standardized as a single product category and may be used as a brand name by vendors. The term may also appear in discussions of laser scanning, structured-light projection, and optical tracking.
