3d the laser scanner are devices capable of delivering an electromagnetic pulse and to receive the reflected signal, by measuring the period elapsed and therefore the distance between the instrument and the point that. The laser beam is beam through a mechanism of mirrors and rotating oscillating that with a change of the angle and Azimuth survey, illuminates the ground in points contiguous. This system works by measuring also thousands of points to the second forming "clouds of points". For each measurement (x, y, z), the system provides the intensity of the signal of return describing the surface of the object with. These are some application fields: Archeology, works of art and cultural goods, working in wood, medical/orthopedic, enterteinment, reverse engineering & rapid prototyping.
