Metrology of Dim Light Sources

Luminescent tags are molecular highlighters. They enable light-based biological assays, visualize biological processes, and are used as diagnostic and

Quantitative Information from Images

Photographs, or optical light images, are spatial records of light reflected or emitted from objects. Thus, they are prospective light measurements. In many

Night Vision Goggle Gain Calibration

NIST cooperates with the three services (Air Force, Navy, and Army) to realize a uniform night vision goggle (NVG) calibration system with low measurement

Air Speed Metrology

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

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

BIB-trap detector

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

Cold Core Technology Platform

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

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

Detector metrology

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

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