Overview
The Leica AT930 Absolute Laser Tracker is a high-precision, portable 3D coordinate measurement system engineered for metrology-grade large-volume applications in aerospace, automotive, energy, and heavy machinery manufacturing. Based on Leica’s proprietary Absolute Interferometric Measurement (AIFM) technology, the AT930 uniquely integrates the traceable accuracy of an absolute distance meter with the real-time velocity and resolution of a heterodyne interferometer—enabling sub-micron-level repeatability and dynamic tracking at up to 1000 Hz without reliance on homing or initialization routines. Unlike conventional laser trackers requiring periodic reacquisition after line-of-sight interruption, the AT930 employs PowerLock—a fully autonomous optical reacquisition algorithm operating across a ±45° horizontal and ±30° vertical field of view—to restore target lock within milliseconds, eliminating operator intervention and preserving measurement continuity. Its monolithic, all-in-one architecture incorporates an integrated environmental monitoring station (temperature, barometric pressure, relative humidity), a high-resolution panoramic color camera (OVC), and ergonomic carrying handle—all sealed to IP54 per IEC 60529—ensuring robust operation in shop-floor environments where dust, temperature fluctuation, and mechanical vibration are prevalent.
Key Features
- All-in-One Metrology Platform: Fully integrated design includes built-in Wi-Fi, hot-swappable battery pack, environmental sensor suite, panoramic camera, and ergonomic transport handle—reducing setup time and external cabling requirements.
- PowerLock Target Reacquisition: Autonomous optical reacquisition across ±45° azimuth and ±30° elevation; resumes measurement within <100 ms after beam interruption—critical for dynamic part inspection and robotic guidance.
- Battery-Powered Mobility: Dual hot-swappable Li-ion batteries support continuous operation for >4 hours per charge; enables cordless deployment in hangars, assembly lines, and outdoor test sites without AC infrastructure.
- Wi-Fi & Remote Control: Native IEEE 802.11ac connectivity supports remote operation via laptop, tablet, or smartphone using Leica’s proprietary Metrology Software Suite (e.g., SpatialAnalyzer, Leica GeoMoS).
- IP54 Environmental Rating: Dust-protected and splash-resistant enclosure compliant with IEC 60529; validated for sustained operation in industrial environments with ambient temperatures from 0 °C to 40 °C and humidity up to 95% non-condensing.
- On-The-Go (OTG) Gravity Alignment: Real-time Z-axis alignment to local gravity vector—essential for jig and fixture leveling, aircraft wing spar alignment, and large-part orientation verification.
- AIFM Core Technology: Combines absolute distance measurement (ADM) stability with interferometric (IFM) speed and resolution—delivering certified accuracy per ISO 10360-12 and VDI/VDE 2617 Part 9 standards.
Sample Compatibility & Compliance
The AT930 is compatible with standard spherically mounted retroreflectors (SMRs), including 0.5″, 1.0″, and 1.5″ diameter targets, as well as active targets such as the Leica T-Mac and iSpace series. It supports both static point measurement and dynamic trajectory capture for moving objects (e.g., robot end-effectors, CNC machine axes). The system complies with IEC 60825-1:2014 (Class 2 laser safety), IEC 61000-6-2/6-4 (EMC immunity/emission), and meets the environmental testing requirements of MIL-STD-810G Method 514.6 (vibration) and Method 500.5 (temperature shock). Data integrity protocols align with FDA 21 CFR Part 11-compliant audit trail configurations when deployed under GLP/GMP frameworks.
Software & Data Management
The AT930 operates natively with Hexagon’s Leica Metrology Software ecosystem—including Leica Infinity for workflow automation, SpatialAnalyzer for advanced GD&T analysis, and GeoMoS for long-term structural monitoring. All software modules support full metadata tagging (environmental conditions, operator ID, instrument configuration), encrypted data export (ASCI, CSV, XML, IFC), and seamless integration with enterprise PLM/MES systems via RESTful API. Firmware updates are delivered over-the-air (OTA) via Wi-Fi, and calibration certificates—including factory-traceable NIST/UKAS documentation—are digitally embedded and exportable with each measurement session.
Applications
- Aerospace: Wing-to-fuselage alignment, tooling verification for composite layup molds, and flight control surface deflection analysis.
- Automotive: Body-in-white dimensional validation, robotic cell calibration, and powertrain component assembly metrology.
- Energy: Wind turbine blade geometry verification, nuclear containment vessel deformation monitoring, and hydroelectric turbine runner alignment.
- Heavy Machinery: Large gear housing bore concentricity, gantry crane rail straightness, and ship hull section positioning.
- Research & Development: Motion capture for biomechanics, multi-sensor fusion with photogrammetry or CMMs, and real-time feedback for adaptive machining.
FAQ
What is the maximum unobstructed measurement range of the AT930?
The AT930 achieves a spherical measurement volume with a diameter of up to 160 meters under optimal environmental conditions and with appropriate SMR selection.
Does the AT930 require external environmental sensors?
No—the integrated environmental monitoring station continuously measures temperature, barometric pressure, and relative humidity, applying real-time atmospheric compensation per ISO 10360-12 Annex B.
Can the AT930 operate without AC power?
Yes—its dual hot-swappable battery system enables fully wireless, portable operation for extended durations without tethering to mains power.
Is the AT930 compatible with third-party metrology software?
Yes—it supports industry-standard communication protocols including TCP/IP, OPC UA, and Leica’s open SDK, enabling integration with SA, PolyWorks, and custom-developed applications.
How does AIFM differ from traditional ADM or IFM-only trackers?
AIFM fuses absolute distance measurement (for long-range stability and no homing) with interferometric fringe counting (for high-speed, high-resolution motion tracking)—eliminating the trade-off between accuracy, speed, and operational flexibility.
