Paper Abstract

In a previous work the monitoring of the fringes pattern shift produced by the interaction of a polymeric film with volatile organic compounds (VOC), by a Pohl interferometric arrangement has been reported. Such fringes shift was measured by a conventional photodetector. In the present work the optimization of an optoelectronic system for detection and quantification of VOC is presented. In this new arrangement a charge coupled device (camera CCD) was used to monitor such fringes shift. The CCD takes advantage of the fact that each pixel can be used as a single photodetector. A program was realized in matlab for the acquisition and processing of the data, which allows to evaluate faster the obtained results. Up to the moment results of the system performance by the measurement of the steady state response of dimethylpolysiloxane (DMPS) to ethanol vapour are reported.
