Laser Radar MV331/351 - Automated, non-contact large scale metrology
The Nikon Laser Radar is the only solution available that provides automated, non-contact measurement capability for large-volume applications of up to 50 meter radius. The new generation of metrology instruments precisely measures large-scale geometry without requiring photogrammetry targets, laser tracker spherically mounted retro-flectors or probes. This revolutionary measuring instrument is suited for repetitive, complex, hard-to-reach, delicate and labor-intensive inspection tasks in automotive, aerospace, renewable energy and many other large scale applications.

Benefits & features
High accuracy and repeatability
The accuracy is dependent on the measurement volume and accuracies range from 24µm (2m distance) to 301µm (30m distance). The impressive accuracy figures meet in general the demands for 3D inspection in a large measuring volumes. The system’s enhanced digital signal processing and increased signal noise ratio guarantee highly reliable measurement data. As a result, Laser Radar is able to perform repeatable range measurements on composites, the material of choice for future aerospace developments.
Fast targetless and non-contact measurement
Laser Radar’s propriety laser reflection technology obsoletes tedious positioning of targets at difficult-to-access locations. Furthermore, the system offers inspection speed up to 2000 points per second in Ultra-fast Vision Scan capture mode. Laser Radar plays in a different league than laser tracker and photogrammetry. Existing inspection stations can be easily converted to measure with the Laser Radar as it can directly measure traditional tooling like tooling balls, photogrammetry dots, trihedrals or even reflective tape. In addition, the Laser Radar’s unique ability to precisely measure through mirrors allow it to see round corners and to measure occluded geometry.
Flexibility in measuring surfaces and finishes
Recapturing one billionth of the reflected laser beam is enough for the Laser Radar to accurately perform a measurement. This means the Laser Radar can scan dark diffuse as well as highly reflective materials or surface finishes of any colour at sharp incident angles. The system’s high signal/noise ratio yields repeatable range measurements on composites, metals and even highly reflective painted surfaces. The non-contact measurement technology also makes the Laser Radar ideal for measuring hot, soft or delicate surfaces.
Covering the complete surface of supersize objects
Two Laser Radar systems are available: MV351 performs range measurement up to 50m, the MV331 up to 30m. Both systems use the same patented technology. The line of sight can be expanded by using dedicated mirrors and taking measurements from multiple Laser Radar positions. All measurement data are automatically referenced to a single contiguous coordinate system, saving time and avoiding human error.
Powerful feature, hole and edge measurement capabilities
The Laser Radar automatically performs feature, edge and trim measurements. With the Laser Radar, feature inspections are much faster than traditional methods without the need for an operator during runtime. The Laser Radar’s edge detection tools also allow users to measure both sharp and hemmed edges with superior accuracy.
Ready for shop floor BIW inspection
For fully automated inline or line-side inspections, Laser Radars can be easily installed on a standard 6-axis robot arm with the built-in robot mounting interface. The MV331’s interface provides a stable mount for a large rage of industrial robots. The robots are used to automatically position the Laser Radar so it can then inspect areas otherwise hidden from the line of sight. The Laser Radar automatically measures alignment points after every move, guaranteeing all measurements are collected in a common coordinate system and ensuring the measurement accuracy is completely independent of the robot.
Fit for any large volume inspection job
In a growing number of industry sectors, Laser Radar is used to perform inspection on giant aircraft parts, composites, wind turbines, concentrated solar panels, antennae, telescopes, ship hulls and propellers, heated surfaces and more.
Large volume metrology software of choice
Customers can choose from a host of large scale metrology software solutions or use the software SDK to directly control the Laser Radar. Spatial analyzer, polyworks and metrolog software are all commonly used in conjunction with Laser Radar. This flexibility in 3rd party software allows customers to use the software of their choice and benefit from the advantages of the Laser Radar without having to re-train on new software.
As the invisible eye-safe laser light travels to and from the target, it also travels through a reference path of calibrated optical fiber in an environmentally controlled module. Heterodyne detection of the return optical signal mixed coherently with the reference signal produces the most sensitive radar possible.
