New Publication on Optics Express

The PolySense team has just published  a new article on Optics Express demonstrating the possibility to use  QTFs as photodetectors in a TDLAS sensor, exploiting the light induced thermo-elastic effect occurring when the laser light hits a QTF surface. In the best experimental conditions, QTF as light detector showed an SNR 6.5 times higher than that obtained by using a commercial amplified near-IR photodetector.

The following link provide access to the article.
