SURFACE DEVICE COMPRISING AN OPTICAL DETECTOR AND A LASER TELEMETER, AND APPLICATIONS FOR HARMONIZATION AND TARGET VIEWING

摘要

The invention relates to a sighting device comprising at least one optical detector (D) operating in a spectal band (F1) and a laser range finder (T) whose transmitter emits a beam whose frequency (s) (F2) are outside of the spectral band (F1). BR/ According to the invention, the device also comprises a removable frequency converter (H) which can be interposed on the path of the laser beam from the emitter in order to transform this beam into a laser beam comprising a frequency or a frequency band (F'1) situated in the spectral band (F1) of the detector. BR/ The invention applies in particular to sighting devices for helicopters.
