Optical alignment compensation system for a gas detection system. Interuniversity Microelectronics Centre
The present disclosure relates to an optical alignment compensation system for a gas detection system, in particular, to an integrated alignment compensation system for an open-path gas sensing system. The optical alignment compensation system of the disclosure is able to compensate for unwanted drifts of a retroreflector. The optical alignment system comprises an array of transceiver pairs, wherein each transceiver pair is configured to transmit and receive light with an optical spectrum in an absorption region of a gas to be detected. Further, it comprises a retroreflector arranged at a ...
