| Outline of Final Research Achievements |
In order to measure directly wind profile in the large facilities, I developed a new direct detection Doppler lidar using a volume Bragg grating filter (VBG). The temperature dependence of the VBG wavelength shift is 11.2 GHz / ℃. This is 1/6 or less of the conventional method of FBG wavelength shift. Furthermore, actually perform wind measurements in the room, and succeeded in obtaining a standard deviation 0.34 m / s in good agreement with the ultrasonic anemometer.
