P3 - Detection of Optical Signal in the Multispectrac Sensor Employing Cavity Enhanced Absorption Spectroscopy

R. Medrzycki & J. Wojtas
In the paper, a preliminary experiments and analyses concerning multi-spectral optoelectronic sensor applying cavity enhanced absorption spectroscopy (CEAS) are described. The main element of this sensor is special photoreceiver system, which is characterized by wide range of the detected wavelengths. Thanks to this, optical signal from many lasers can be measured using one photoreceiver. Moreover, in one cavity, a value of absorption coefficient at a few different wavelengths can be determined parallel. Typical CEAS system...
