Abstract
The aim of the invention is to provide an architecture of a laser imager having high spatial resolution, compatible with an application installed on board a vehicle, in particular on board an aircraft. For this purpose, the invention proposes the generation of a piece of wide-field laser ranging information by a suitable remote optical system. An example of a piece of equipment (1) according to the invention installed on board an aircraft moving in an environment that is likely to contain obstacles (4), in particular an aircraft on the ground, includes a laser range finder (11) coupled to an optical fibre (F1) emitting laser pulses (I), which is itself coupled to an optical system providing an interface with the environment (12) via an optical cross-connect (13) coupled to a covered optical fibre bundle, in the form of laser illuminations (Fi). An echo detector (14) detecting echoes of the laser pulses reflected by an obstacle (4) in the environment is connected to a processing unit (15) for processing the echoes (Er), which is itself connected to a central data unit (16) containing data relative to the conditions of movement of the aircraft and to a display system (17) for display…
