A reflection mirror is capable of autorotation about at least an in-plane horizontal axis thereof, and a support ring is attached to the reflection mirror so as to be capable of rotating about an in-plane vertical axis and the in-plane horizontal axis of the reflection mirror. Further, a laser pointer unit formed by inserting a laser pointer into a sleeve pipe is attached to the support ring so as to be oriented toward an in-plane of the reflection mirror. Furthermore, a guide scope is attached to the support ring such that an optical axis thereof matches an optical axis of the laser pointer unit.

摘要： An object of the present invention is to provide a method for preventing turbulence-induced accidents that can expand a detection range to about 20 km without increasing the size of a device or increasing the energy consumption, can perform planar distribution monitoring of turbulence when the turbulence is detected in the flight direction and also can output a signal for autopilot steering input that decreases the fuselage shaking when the turbulence is difficult to avoid, as well as to provide a device having those functions. In the method for preventing turbulence-induced accidents according to the present invention, an optical remote airflow measurement device of a Doppler lidar system using a laser beam is used to routinely enable distant turbulence to be detected by fixing a laser emission course in a flight direction and taking a long integration time of a reception signal, and to enable planar distribution of the turbulence to be displayed when turbulence is detected, by scanning the laser emission course in a horizontal direction and switching an image display to a two-dimensional display.
