The project includes a photodiode with a special focusing optics: the reflected radiation is concentrated in order to increase efficiency; two selective dichroic mirrors direct the radiation of different wavelenght in the right path and to a fixed-speed rotating mirror for scanning. The prototype scans the area with a frequency of 20.000 readings per second; if a target is identified, it is illuminates with pulsed radiation at 1550nm (eye-safe wavelength).<\/p>\n<h3>Results<\/h3>\n<p>The lidar part was developed according to classic scheme: for distances limited to a few meters (4-6m) the signal is sufficiently intense and the attenuation of the dichroic mirror don&#8217;t significantly affects transmitted and reflected radiation. The evaluation of the installed prototype is positive, the system satisfies the specifications.<br \/>\nThe lighting part of the target allows to meet the application specifications so allows to maintain impulsive radiation for as long as the object remains in the scanning area.
