Air Speed Metrology

Ongoing
NIST's versatile wind tunnel is used to calibrate customers' airspeed sensors and to conduct research on the design of novel anemometers, the responses of

Aperture area measurements

Ongoing
Radiometric and photometric measurements require defining apertures. The accuracy to which these measurements can be accomplished requires minimization of the

BIB-trap detector

Ongoing
The goal of the BIB-Trap Detector project is to develop a detector composed of solid-state devices that can be used as a reference detector for calibrations in

Climate Science

Ongoing
The National Institute of Standards and Technology (NIST) is working to advance measurement capabilities needed to study the world’s climates. Climate Science

Cold Core Technology Platform

Ongoing
We are building a cold-atom based sensor program that represents a new approach to metrology—to establish a set of chip-scale tools that enable real-world use

Color and appearance

Ongoing
We are developing instrumentation, standards artifacts, and measurement protocols to characterize appearance attributes including color, texture, and gloss

Detector metrology

Ongoing
High performance optical radiometers with selected optical detectors are being designed, characterized, and calibrated in the Optical Radiation Group for the

Diffraction effects in radiometry

Ongoing
We want to quantify the breakdown of geometrical optics when computing the throughput of optical systems for the purpose of calculating "diffraction corrections

Earth Energy Budget

Ongoing
The goal of this project is to extend and improve the measurements of the key climate record of the long-term balance between Earth absorption of solar energy

Extreme ultraviolet optical constants

Ongoing
In the vacuum ultraviolet and extreme ultraviolet (EUV), the indices of refraction of all materials become complex: N = n + ik , or N = 1- d + ik . Here, n is

Fiber-optic Frequency Comb Development

Ongoing
To support comb-based measurements outside the metrology laboratory, we develop high performance, robust frequency combs based on fiber-optic technology.
