This paper presents a proof of concept for monitoring masonry structures using two different types of markers which are not easily noticeable by human eye but exhibit high reflection when subjected to NIR (near-infrared) wavelength of light. The first type is a retroreflective marker covered by a special …

Abstract A setup is designed and constructed to perform specular reectance spectroscopy on an enzymatic reaction, while simultaneously monitoring the heat produced by the reaction using a FLIR camera. The spectrum of ethanol was recorded using two MCT detectors and showed clear overlap with literature …
