| 摘要 |
<p>The invention concerns a system for displaying in space of a trajectory between at least a transmitter and a receiver, one or the other being mobile. Said spatial display system of a trajectory between at least a transmitter and a receiver, one or the other being mobile, the trajectory being physically represented by one or several laser light beams forming one or several beams from at least one transmitter, is characterised in that said transmitter is protected such that its operating conditions are not altered by external conditions, whether it is rain, fog or dust. Said transmitter can also transmit in one or several wavelengths or wavelength ranges and in several continuous transmission modes, modulated and Q-switch.
