Abstract

The device includes an inspection rod cluster (10) comprising a central cylindrical body (45) and a plurality of arms (46, 48) extending radially with respect to the cylindrical body (45). Guide bars (49) for the inspection rod cluster (10) in the guide elements of the guide tube may be fixed to the end of at least two arms (48), opposite the cylindrical body (45), and rotary inspection probes (47) may be fixed to the end of the other arms (46). Preferably, the probes (47) are probes for remote optical measurements by the ladar method.
