Abstract:
An atmospheric cloud height, humidity profile, or temperature measuring method and arrangement are provided. In the method, pulsed laser signals (14) are transmitted through transmission optics (2, 3, 4, 5, 6) to the atmosphere and the signal (15) reflected or scattered back from there is detected. An interference filter (3) is used in the optics, in order to stabilize the transmitted optical power to the center wavelength of the interference filter (3).
