<p>PROBLEM TO BE SOLVED: To display a plurality of pieces of control information on a single screen and to save the space of a control tower by totally displaying a number of pieces of information by synthesizing first and second pieces of display information and visibly displaying the information obtained by the synthesis. SOLUTION: A light transmission part 1 excites a laser beam with a wavelength for observing turbulence and outputs a prescribed laser energy to an optical scanning part 3 with a prescribed pulse width. The optical scanning part 3 transmits reflection light to a light reception part 4, and the light reception part 4 performs heterodyne light detection by the reflection light and converts signal reception strength to an electrical signal. The light reception part 4 outputs the reception strength signal to a signal-processing part 5. Then, the signal-processing part 5 detects the generation position and range of turbulence and turbulence strength based on a specific algorithm by the inputted reception strength signal, converts them to XY coordinates for display, and creates turbulence display information for display. The turbulence display information for display is sent to a display 6 from the signal-processing device 5 for visible display.</p> |
