Abstract: The present invention finds its application, in general, in the agricultural sector. In particular, the solution concerns a transportable sensor device, which is essential for optimizing and automating the treatment processes that must be carried out on fruit plants in general. Ultimately, the sensor device according to the teachings of the invention can be used to acquire a two-dimensional map of a row of plants, without going through the acquisition of an image in the visible field which would involve the use of optical sensors, whose use presents various problems; instead reconstructing equivalent images (i.e., maps describing a row of plants seen from its side) which are very significant from the point of view of their information content. In fact, such equivalent images acquired by the device indicated in the invention do not require to be reprocessed through recognition programs, but directly contain the information that is needed in many types of applications. The invention is based on an innovative use of infrared radiation active sensor technology, which however requires the design and implementation of a new type of sensor device, built with specific new features, such as the use of very directive radiation, in narrowband and on a plurality of carriers. Furthermore, also the geometric structure, and the shape, of the sensor device itself must have some particular features, which make it suitable for performing a sort of scanning of entire rows of plants; everything in a simple way and without the need to resort to complex handling mechanisms.
