Infrared spectroscopy is one of the oldest and well established experimental techniques for the analysis of secondary structure of polypeptides and proteins. It is convenient, non-destructive, requires less sample preparation, and can be used under a wide variety of conditions. This review introduces the recent developments in Fourier transform infrared (FTIR) spectroscopy technique and its app...

Active infrared thermography has been used for the detection of sub surface defects in road materials. The step heating method was selected, and two different infrared cameras selected. Defects were detected with an heating phase as short as 60 seconds. Some images treatments were employed, and have been able to extract signal in spite of the porosity and of the high heterogeneity of a road mat...

The aim of this review is to present the state of the art of neurophotonics, a recently founded discipline lying at the interface between optics and neuroscience. While neurophotonics also includes invasive techniques for animal studies, in this review we focus only on the non-invasive methods that use near infrared light to probe functional activity in the brain, namely the fast optical signal...

The evolution of papermaking from XII century, in Europe, was characterized by continuous changes of fibrous and non-fibrous materials as cellulose, wood pulp, sizing agents, fillers and coatings. In this study, the composition of many ancient paper documents is analysed by means of non-destructive Fourier Transform Infrared Spectroscopy (FTIR) in order to identify the main components of paper ...

It is important for near-infrared spectroscopy (NIRS) and imaging to estimate the sensitivity of the detected signal to the change in hemoglobin that results from brain activation and the volume of tissue interrogated for a specific source-detector fiber spacing. In this study light propagation in adult head models is predicted by Monte Carlo simulation to investigate the effect of the superfic...

In this paper a novel approach is proposed which combines simultaneously advantages both of pulse (PT) and modulated (MT) infrared thermography. In a nondestructive evaluation perspective, the specimen is pulse-heated as in PT and the mix of frequencies of the thermal waves launched into the specimen are unscrambled by performing the Fourier transform of the temperature evolution over the field...
