Abstract
A telemetric optical-radiation laser transmitter 5 outside an aperture 2 sends a beam to a point 14 scanned over the charge surface 1, via a rotating assembly 7 of deflectors, one deflector 11 oscillating with a periodicity related to the rotation of the assembly. A telemetric receiver 19, sensitive to the radiation from the transmitter 5 in a selected wavelength range, receives radiation re-transmitted from the point 14 through an aperture 3. A thermometric receiver 6 receives thermal radiation from the point 14 along a path coinciding with the path of the transmitted optical radiation.
