Where a light meter has a sensor that tells the camera how much light is passing through the lens, SMAP’s radiometer measures and records the changing amount of radio frequency microwaves that are emitted by Earth’s surface. WebWorking of Infrared Thermometers. Similar to visible light, it is also possible to focus, reflect, or absorb infrared light. Infrared thermometers employ a lens to focus the infrared light emitting from the object onto a detector known as a thermopile.
