Daylight rejection with a new receiver for potassium resonance temperature lidars
Abstract
For daytime operation a new receiver for potassium resonance temperature lidars was developed that includes a twin Faraday anomalous dispersion optical filter and a high-performance photon-counting avalanche photo-diode instead of a photomultiplier. The design of a flat spectral filter shape over the lidar scan range avoids instrumental error on the temperature results. Initial temperature measurements under daylight conditions were realized.
