Abstract

The proposed condensation hygrometer contains a light source, a controlled thermoelectric cooler, a temperature meter, a photodetector, a hollow lightguide, and a computing unit. The lightguide is optically coupled with the light source and the photodetector. The thermoelectric cooler is designed for cooling the lightguide. The outputs of the temperature meter and the photodetector are connected to the corresponding inputs of the computing unit. The outputs of the computing unit are accordingly connected to the control inputs of the light source and the cooler.
