Figures A and B demonstrate how dew point is measured by a dew point hygrometer. In Figure A, light is transmitted from a laser and ¨ç reflected off the mirror onto a receiver that measures the intensity of the observed light. When the mirror temperature is above dew point and the intensity of the transmitted light is 10 mW/cm2, the intensity of the observed light is ¨èthe same. In Figure B, when the mirror temperature is at dew point, dew drops cover the ¨ésurface of the mirror. When the transmitted light hits the dew drops, it becomes ¨êscattered. As a consequence, compared to the intensity of the transmitted light, that of the observed light measured by the receiver is ¨ëincreased.
