OLES - Major Activities1. Maintain metrology activities and laboratories for

equipment unique to law enforcement and criminal justice agents and emergency responders.

2. Conduct applied research supporting development of technology and metrology.

3. Author user guides, minimum performance standards, and technical reports.

4. Design methods for examining evidentiary materials.5. Provide technical advice and assistance to criminal

justice, public safety, emergency responder and homeland security communities.

OLES - Metrology Activities Work with NIST technical divisions, manufacturers, user

communities, and Standards Development Organizations (if applicable) to: – Develop suitable metrics for device and system evaluation – Develop industry-standard test procedures and artifact standards– Design, develop, and maintain suitable test beds (including emulation

of probable scenarios, etc.)– Develop application-specific performance standards and user guides – Provide precision measurements support to NVLAP accredited

laboratories

The National Academies Report on Forensic Sciences

NIST was the primary author for a standard on the metrological traceability of dimensional measurements. The purpose of this report is to provide guidelines for demonstrating the traceability of dimensional measurements to the SI unit of length (the meter). Intended for design, drafting, mechanical, manufacturing, production, tool/gage, quality, process and project engineers, CAD/CAM/CAE specialists, inspectors and educators across a broad range of global manufacturing. Special emphasis on aerospace, automotive, medical device, precision instrumentation and related industries.

Laser Tracker Standards

NIST is also the primary author of the world’s first standard for laser trackers. The standard describes how trackers are specified for accuracy and how both tracker manufacturers and users can test the tracker to check the specifications.

The test positions are optimized to reveal errors associated with the optical-mechanical design of this class of insturments.

The Large-Scale Coordinate Metrology (LSCM) Group provides special tests on a fee for service basis of long length standards upon customer request. The group performs a feasibility study of all requests to determine if we can provide an appropriate calibration.In the past, the LSCM Group has provided special tests and length calibrations for fiber optic cables standards over 1 km in length, for special 5 m length rods used in the nuclear power industry, and for ball bars up to 3 meters in length.
