CompAct eye-safe Lidar source for AirBorne lasER scanning
CompAct eye-safe Lidar source for AirBorne lasER scanning Monitoring sensitive areas, such as overseas gas extraction platforms, power plants and maritime ports is of paramount importance for the safety of workforce and the protection of the buildings. Sensors are usually consisting in cameras, which are placed on roofs or UAVs to have a more complete overview of the instalments and of the surroundings. Among monitoring techniques, however, Light Detection and Ranging (LIDAR) systems have proved to be more effective and precise for remote sensing applications, ranging from the detection of obstacles for automobiles and aircrafts, to the topographic investigation of landscapes, and to the detection of wind turbulence and hazardous gases or pollutants. A key device of the Lidar system is the laser source, whose function is to illuminate the targeted zone and provide enough signal for the detectors. The quality of the sensing thus strongly depends on the type of source employed, in terms of wavelength, pulse width, average power, since the combination of these parameters defines the precision and reliability of the overall system. However current LIDAR systems are bulky and characterized by high power consumption, which do not make them suitable for installation on UAVs. The CALIBER project aims at studying and developing a new generation of eye-safe Lidar sources able to combine high repetition rate and high peak power in a compact and lightweight format. The project is carried out in collaboration between Italy as NATO Country together with Partner Countries Israel and Finland.
