A compact and simple 355-nm direct-detection Doppler wind lidar (DDDWL) was developed
to measure the line-of-sight (LOS) wind speed of the background atmosphere from
atmospheric molecule return signals with and without aerosols and clouds. A receiver
design with a Fabry–Perot etalon interferometer (FPEI) without an inside deposited step
coating or fiber coupling is considered for the DDDWL using the double-edge technique.
The receiver with the double-edge technique uses a FPEI and wedge prism to form a double …

We developed a simple 355-nm direct-detection Doppler wind lidar (DWL) for atmospheric
motion study. The 355-nm direct-detection DWL uses the double-edge technique for a
receiver with Fabry-Perot etalon interferometer and a wedge prism to form a double-edge
filter. Preliminary experimental line-of-sight (LOS) wind measurements were made to
investigate wind measurement performance of the 355-nm direct-detection DWL on July 22,
2021. Although the observational range limit depends on its telescope area and …
