Split Laser System for Environmental Monitoring

Environmental monitoring — the assessment of air, water, and soil quality — is highly important to oil and gas exploration companies, landowners, regulatory agencies, municipalities, and any organization measuring emissions and pollutants. The majority of monitoring technologies, however, are expensive and labor intensive, often requiring sample collection and preparation (i.e., external lab analysis) that can dramatically alter the sample and its inherent components. Of those technologies that do allow for in-situ analysis, few are amenable to measurements under harsh conditions, such as high temperature and/or pressure.

Measuring Tiny Forces with Light

Photons have no mass, but they have momentum. This allows researchers to use light to push matter around. Scientists at the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST) have taken advantage of this property to develop devices that can create and measure minute forces, an area traditionally underserved by the metrology community.

Laser Scanning Technique for Testing Fire-Damaged Concrete

Research at The University of Nottingham (UK) and the University at Ningbo (China) has found that laser scanning is a viable structural safety technique to detect the damaging effects of fire on concrete. Concrete is the most extensively used construction material worldwide with an average global yearly consumption of 1 cubic meter per person. Fire is one of the most serious potential risks to concrete structures such as bridges, tunnels, and buildings.

3D Measurement and Visualization of Displacement and Strain Fields

The Naval Research Laboratory (NRL) has developed a metrology workbench for the measurement and visualization of displacement and strain fields in three dimensions. The workbench uses two or more cameras to image a specimen, and includes custom software that implements the 3D Meshless Random Grid method.

Selecting the Right Material for 3D Printing

Materials must be suited to the application in order to have successful results. The properties of any material become increasingly important as a product progresses from concept and functional prototyping to production.

Hydraulic Carts Streamline Structural Tests for Aircraft

The Flight Loads Laboratory (FLL) at Armstrong Flight Research Center tests the strength and endurance of aircraft structures using hydraulic actuators to apply forces that simulate the stresses of takeoff, flight, and landing. The contract to build the FLL’s next-generation hydraulic controller system went to Moog Inc., an East Aurora, NY-based company that specializes in motion control systems. The company designed a multi-function mobile cart that not only houses the hydraulics for up to eight actuators, but also includes most of the necessary electronics, which were previously housed in the control room.
