The method comprises the steps of (a) providing a transparency (20) of an optical image of a scene (22) in the visible band; (b) directing the infrared radiation from an infra-red source (34) through the transparency and collimating the radiation with a collimator (30); (c) detecting the infra-red radiation which passes through said transparency with a device which generates an electronic image corresponding to the scene (22), and (d) providing a visible output of said detected infra-red radiation using a device (40) such as a video printer. <IMAGE> |
