<p>A device for viewing an object field (8) containing intense light sources (5) which could be disturbing or harmful to the human eye (7). Light (1) from the object field (8) is focused at a focal plane (2) located within a layer of photochromic material. An intense light source (5) produces an opaque mask on the photochromic layer. This mask matches the location and shape of the image of the intense light source at the image plane (9). A lens system permits the viewer to view the image plane (9) to obtain an image of the object field with light from the intense light source dimmed by the opaque mask in the photochromic layer. Dimensionality reduction can be achieved by folding the optical path by means of mirrors or prisms, or arranging a multiplicity of devices in array formation.</p> |
