KINO
Nature as seen through a first generation night vision device (starlight scope). All shots are made with the use of an infrared illuminator. Starlight scopes work by gathering ambient light (from stars and moon) and infrared light (from the IR illuminator). The light is gathered by a special layer of material that ejects electrons when struck by photons. The electrons pass through a glass vacuum tube through which they are accelerated by electrical fields (powered by the battery). The electrons then strike a phosphorous membrane at speeds higher than their initial speeds (since they’ve been accelerated by electrical fields). The phosphorous membrane in turn releases more photons into the eyepiece than have originally been gathered by the intaking membrane since the electrons that knock out the photons have been accelerated. This is how night vision light aplicfication works. This is totally different from thermal vision which senses the “blackbody radiation” – the heat signature of an object or digital night vision where a CCD sensor is used to convert infrared light to the visible spectrum.
