METHOD FOR DIRECTIONALLY RADIATING AND/OR FOR DIRECTIONALLY RESOLVED RADIATION DETECTION

摘要

The invention relates to a method for directionally radiating, in particular the walls of a cavity and/or for directionally resolved detection of radiation, in particular emitted or reflected by cavities by means of a light waveguide. In order to perform radiation, a visible light spectrum radiation or the radiation of ranges adjacent on both sides thereof is used. Said radiation is emitted by at least one light source, preferably a laser, and is injected into the front face of the light waveguide (5). The injection is carried out according an angle which is selectable and modifiable with respect to the axis of the light waveguide. In addition or alternately, a radiation inciding upon the rear surface of the light waveguide and emerging from the front face thereof can be detected in an angularly resolved manner.
