The sooner you can understand and get comfortable with that difference the more you will enjoy this incredible technology Why things look the way they do Ihe Voyager s thermal imager makes video images from differences in heat not from the light you see every day It senses the minute differences in heat between objects and in white hot mode displays the warmer objects as white or lighter shades of gray and colder objects as black or darker shades of gray Everything you encounter in your day to day existence gives off heat even ice Chances are that the hotter something is the easier it will be to see While most things give off their own heat some things actually reflect the heat given off by other things Water and polished metal for example aren t as hot as they appear when they reflect sunlight What s more some things that are the same temperature or close to it look different because of their different surface textures IR energy doesnt go through glass efficiently so Voyager won t let you see through glass Thermal imagers are passive they only receive incoming energy They don t see through anything While you might think you are seeing through the hull of the vessel on the right to see the bulkheads and heat from the engine youre not These elements are actually changing the temperature of the hull itself allowing you to see the bulkheads and the hot engine room As you experiment with your Voyage
