Finding Buried Objects With Infrared Photography
Infrared photography measures the heat that emanates from objects, and captures it on film. It has many applications to science and industry, and can even in many cases “see” objects buried under the earth.
The basis for infrared’s ability to detect underground objects is the difference in the way objects processing heat, when compared to neighboring dirt, farmland, etc. In its most advanced application, researchers have used infra red technology to see objects as deep as 38 feet below the earth.Such findings are subsequently followed up by radar examination , which can “see” reliably to 20 feet.
A very obvious application has been the detection of underground piping systems. Since piping often transmits material that is hotter or colder than the surrounding area, it creates a perceptible difference in the infrared emanations coming out from the surface above the object. Heating pipes, for example, will noticeably heat up insulation and the surrounding area, and make a very definite infrared imprint. At times such piping can be detected even when it runs under asphalt or concrete.
Any underground substance which transmits heat differently than the surrounding soil or vegetation can be investigated through infrared photography. This includes storm water drains, sewer lines, distribution piping and supply water mains.
Ariel infrared photography has been used for detection of underground petroleum piping. Surrounding environmental substrate has different effects on ambient temperature, however the piping can be traced though farmland, dirt roads, and even under asphalt surfaces.
Infra red detection of underground phenomena is usually done from a raised platform such as a tall truck or a helicopter. Quality examination can be made at night when the surface gives off the heat absorbed during the day.
