Climate Science

Ongoing
This program encompasses multifaceted efforts to advance the metrology of climate science. Projects include: development of ultra-high accuracy optical standards and technologies to determine greenhouse gases (GHGs) concentrations, atmospheric lifetimes, and aerosol radiative forcing development of

Laser Power and Energy Meter Calibration

Ongoing
For calibrating instruments used to measure the power or energy emitted by a laser, or single photon source specially designed primary and secondary standards consisting of calorimeters, pyroelectric detectors, thermal radiometers, photodiode traps and recently superconducting nanowire single-photon

Material Qualification

Ongoing
Objective To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological

The Photoforce Project

Ongoing
Traditional power meters measure the power of a laser beam by absorbing its energy. Radiation pressure (photon momentum) permits the measurement of a beam’s power by “absorbing” its momentum and reflecting its energy. Light reflecting from a mirror causes a force that is proportional to its optical

Precursor Material Qualification

Completed
To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological, size

Sensing and Imaging of concealed objects

Ongoing
Threats to personal and collective safety abound in our society. The Security Technologies Group (STG) performs research to advance the technology and measurement science of security imaging and sensing. This work includes the establishment of test and evaluation tools, reference test beds, test
