Austin Richards takes readers on a visible journey of the electromagnetic spectrum past the diversity of human sight, utilizing imaging know-how because the potential to 'see' invisible mild. Dozens of colourful photographs and transparent, concise descriptions make this an exciting, obtainable technical publication. Richards explains the sunshine spectrum, together with obvious gentle, and describes the complicated imaging applied sciences that let people to synthesize our personal model of 'alien' imaginative and prescient at diverse wavelengths, with purposes starting from fireplace combating and legislations enforcement to botany and medicine.

For this reason, thermal imaging technology facilitates the detection of many objects in total darkness and, in many cases, makes it possible to measure their surface temperatures. Midwave and longwave infrared light can also penetrate smoke and mist, facilitating observation in conditions that make visible-light imaging impossible. For instance, a person lost on a moonless night in the woods without a flashlight or signal flare would be very difficult to find from the air with visible-light imaging.

16 is a visible-light image of a transformer bank near sunset. There is no visible indication that the transformers are energized, since they only heat up 10–15°C in operation, which is not nearly hot enough to make them glow with visible light. The right image in Fig. 16 is an MWIR image of the transformers taken at the same time. The heating caused by an electrical load is apparent, as indicated by the pseudocolor. In this representation, white is the hottest color, followed by yellow, orange, and red, with purple and black representing the coolest parts of the scene.

Aspx 32 Chapter 2 When we use technology to image the world in the thermal infrared waveband of the electromagnetic spectrum, we are exploring unknown territory, seeing things that no animal has ever seen. This is truly alien vision! Thermal images can look very different from visible-light images of the same scene. This is especially true in darkness, or what we call darkness because there is little or no visible light. The thermal infrared world is never really dark, and objects that are just slightly warmer than the background around them can be detected with thermal imaging, provided they do not have shiny surfaces.
