LOD is housed in an external sensor box which must be installed above the AUTOSORT. A relatively large space is required. The LOD is able to detect and sort out unknown objects (NIR limits) from a material stream. DEEP LAISER is much more compact and flexible because it is integrated in the AUTOSORT. Moreover it is versatile. Detection of unknown material (NIR limits) like LOD, for use with Intelligence Object Recognition or as sensor for DEEP LEARNING.
