Princeton Docket #
10-2584-1
Researchers
from Princeton University and the
STFC Rutherford Appleton Laboratory (UK) have developed a novel method of high
sensitivity molecular detection based on detection of refractive index changes
around the absorption line. This
method employs heterodyne interferometric measurement with a frequency...

Princeton Docket # 11-2700-1
Detection of molecular species is of importance in a number of industrial, health and atmospheric monitoring applications. Existing spectroscopic gas sensing instrumentation has some fundamental limitations, primary due to the fact that signals carrying the useful information are encoded in light intensity, thus the measurements...
