Infrared Imagery in General Infrared imagery is often a grayscale picture whose scales (or shades of gray) represent the differences in temperature and emissivity (opposite of reflectivity) of objects in the image. As a general rule, objects in the image that are lighter in color are warmer, and darker objects are cooler. No object is detected in visible light wavelengths (400-700 nm) rather, it detects infrared wavelengths (3000-5000nm & 8000-14000 nm). Lights and other relatively hot objects are evident, but as a result of their heat--not light emissions.
When an image is taken with an infrared camera, it is often recorded onto videotape and/or digitally saved to an on-board storage device. The images are downloaded, opened in specialized software and modified in a number of ways to enhance their value to the end user, like colorizing the images or adjusting the span and temperature to highlight a particular object in the image. |
