Direct Scanning Laser Trackers – A New Era for Quality Control

Why It Matters

By removing manual steps and reducing inspection downtime, manufacturers can boost throughput, lower scrap, and address skilled‑labor shortages, giving them a competitive edge in high‑precision sectors.

Key Takeaways

• Direct scanning removes need for physical reflectors
• ATS800 combines reflector tracking and scanning in one unit
• Inspection times drop dramatically, boosting line throughput
• Reduced training lowers labor costs and error risk
• Enables in‑situ measurement of large, complex parts

Pulse Analysis

Laser trackers have been the workhorse of large‑volume metrology for decades, especially in aerospace, energy and shipbuilding where parts can span several meters. As manufacturers adopt digital‑twin strategies and push tolerances tighter than ever, the traditional reflector‑based approach is increasingly seen as a bottleneck. Operators must manually place targets, which consumes valuable floor time and introduces human error. The pressure to keep factories compact while coping with a skilled‑labor shortage further amplifies the need for faster, more autonomous inspection solutions.

Direct scanning laser trackers eliminate the target‑placement step by projecting a measurement beam directly onto the part’s surface. Hexagon’s Leica Absolute Tracker ATS800 integrates this capability with conventional reflector tracking, delivering a true 2‑in‑1 instrument that can switch modes on the fly. The system automatically maps edges and contours across volumes exceeding 100 m³, feeding point‑cloud data into CAD or digital‑twin models without manual post‑processing. By embedding the scanner into robotic cells or automated guided vehicles, manufacturers can run continuous inspection loops, cutting cycle times by up to 50 % while preserving sub‑millimeter accuracy.

The shift toward direct‑scanning trackers promises measurable ROI for firms battling scrap rates and labor shortages. Early adopters report up to 30 % reduction in inspection‑related downtime and lower training expenses, translating into faster time‑to‑market for high‑value assemblies. As more OEMs integrate point‑cloud data into predictive maintenance and quality‑analytics platforms, the ATS800’s ability to generate dense, traceable geometry positions it as a cornerstone of Industry 4.0 metrology ecosystems. Vendors that combine hardware innovation with robust software pipelines will likely dominate the next wave of precision manufacturing.
