Title: Non-destructive, in-situ evaluation of water presence using thermal contrast and cooled detector

Abstract

Exemplary methods for detecting presence of water in a sample include: heating a light source to a predetermined temperature at which the light source emits thermal radiation; placing a sample between the light source and a detector; transmitting the thermal radiation from the light source through the sample and onto the detector; and determining a presence or an absence of water within the sample based on the thermal radiation transmitted onto the detector. Exemplary systems for detecting presence of water in a sample are also disclosed.
