Color and appearance

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

Detector-based color scale

Until recently calibrations of tristimulus colorimeters were performed against lamp standards. However, the uncertainty of these source-based calibrations

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

Extreme ultraviolet optical constants

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 the

Frequency Comb Spectroscopy

We use frequency combs based on ultrafast mode-locked lasers to perform precision spectroscopy in the near- and mid-infrared domains, for rapid, high

Fundamentals of Deformation

This project provides new measurement methods, property data and simulations for areas critical to US manufacturing, describing the mechanisms responsible for
