(EN) APPARATUS FOR VISUALIZING A MOVABLE RADIATION SOURCE
Abrégé
(EN)

An apparatus for visualizing a movable radiation source, the apparatus comprising: a radiation angular position sensor arranged for generating an angular position, with respect to a sensor axis, of a radiation source emitting radiations in front of said radiation angular position sensor; a camera having a camera axis distinct from the sensor axis; a light diverter arranged in front of said radiation angular position sensor for diverting toward the camera, light originally emitted in front of said radiation angular position sensor toward the radiation angular position sensor, the light diverter being arranged to not change the direction of radiations emitted in front of said radiation angular position sensor; and a composite image generator arranged for adding to a camera image captured by the camera a radiation source marker at a position derived from said angular position and automatically scaled to the camera image size and resolution.
