Performing infrared imaging and analysis on buildings or structures is challenging on a good day. More often than
not, scanning an entire multi-story building will take several days. It requires patience from the thermographer
because he has to let the sun to do its job solar loading the building, or, he may have to wait for the building to radiate
its solar load in the cool of the evening. Usually this takes a "whatever the study requires" state of mind and the days
are long. An experienced eye is also required to understand the nuances of construction and subtle temperature variations as
they appear in an infrared image. Even with optimal conditions and a good uniform solar load, a strong thermographic
indication can trip you up when it travels around a corner or into shadows. This condition can frustrate the
thermographer, and also make the job longer because he has to wait for the sun to load into the next area of interest to
chase out the indication. How do you get around this?
This paper presents thermographic techniques to help image indications that run from uniform solar load around
corners or through shadows.
