Research Abstract |
The performance of the new direct detection Doppler lidar using narrow band interference filters for measuring wind speed distribution was evaluated. A light source is an eye-safe 1. 5-micrometer laser. Total efficiency improved 50% as compared with the conventional FBG method. Since steep edge was obtained with three interference filters, the maximum transmittance was 30%. Improvement in efficiency is expected by using one low loss interference filter.
