  • Device for locating radiation sources
    Patent number: 6380541
    Abstract: This device comprises a chamber (4) with a pinhole, the walls of the chamber acting as shielding (6) that absorbs radiation. The chamber contains means of forming images of the sources, due to radiation, and the area in which the sources are located, due to visible light from this area. A part (36) of the shielding in which the pinhole (32) is located, is free to move and is fixed to an optical system (34) capable of providing sharp images in visible light over the required field depth by replacing the pinhole for the formation of the image of the area, and vice versa for formation of the image of the sources.
