Thermal acoustic imaging (TAI) is a proprietary active thermographic inspection process developed by Pratt and Whitney (P&W) in 2005; TAI is a nondestructive testing (NDT) method to detect internal and external cracking of hollow core turbofan engine fan blades.
In addition, there are two mutually exclusive approaches in thermographic inspection: passive, in which the features of interest are naturally at a higher or lower temperature than the background and no energy is introduced to the system being inspected. For example, the surveillance of people on a scene using a thermal imaging camera.
In 2000, the Los Angeles Times called the thermal imaging camera "[p]erhaps the best advance in fire equipment in the last 25 years—and the most expensive". [23] Fire departments have pursued various sources and methods to fund thermal imaging cameras including direct budgeting, [6] grants, [9] and charity donations, [24] among others.
In infrared thermography, thermal radiation is detected and measured with infrared imagers, also known as thermographic cameras or radiometers. The imagers contain an infrared detector that converts the emitted radiation into electrical signals that are displayed on a color or black and white computer display monitor.
Thermogram of a traditional building in the background and a "passive house" in the foregroundInfrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science.
On October 4, 2022, the company announced that NASA will use its thermal LWIR camera module, the Boson, in its design of an inflatable re-entry heat shield. [ 69 ] On October 25, 2022, the company was awarded $48.7 million (USD) to provide Maritime Forward Looking Infared (MARFLIR) II sensors and variants of the SeaFLIR 280-HD surveillance ...
