Nikon’s New Laser Radar for Large Scale Metrology Applications

Nikon Metrology Laser-RadarNikon Metrology has introduced the new MV331 and MV351 for large scale, automated, non-contact metrology. The new Laser Radar slashes inspection time compared to traditional measurement systems and can be used in aerospace, automotive, renewable energy

The Laser Radar offers non-contact inspection, true single-person operation and supports off-line programming for completely automated and unattended operation, reducing operating costs. The Laser Radar’s patented technology enables direct surface and feature measurements at high data rates which eliminates the need for photogrammetry targets, spherically mounted retro reflectors (SMRs) and handheld probes. The MV331/351 also slashes inspection times with high speed ‘vision scans’ that capture up to 2,000 points per second. For manual measurements, the multi-zoom overview camera allows the operator to locate the target part within a larger workspace.

Designed for accurate feature inspection

The Laser Radar can automatically perform feature, edge and trim measurements; improving product quality. With the Laser Radar, feature inspections are much faster than traditional methods and can be completely automated. The Laser Radar’s edge detection tools also allow users to measure both sharp and hemmed edges.

Existing inspection stations can be converted to measure with the Laser Radar as it can directly measure traditional tooling like tooling balls, photogrammetry dots, trihedrals or even reflective tape.

Redesign of internal components, improved environmental control create longer periods between calibrations and less measurement susceptibility due to environmental factors. This allows the Laser Radar to run a full day between field checks, even in a manufacturing environment.

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. Laser Radar can scan dark diffuse as well as highly reflective materials or surface finishes of any color 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.

Ready for shop floor use

For fully automated inline or line-side inspections, Laser Radars can be 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 has replaceable external air filters. In addition to the new filters, positive air pressurization can be used to keep dust and other airborne particles out when working in harsh manufacturing environments.

Seamless integration with common large scale metrology software

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. The Laser Radar comes with a small footprint cabinet including a high-performance PC and peripherals.
