When was thermography first used?
By 400 BC, physicians commonly employed a primitive form of Thermography: they applied a thin coat of mud to a patient's body, observed the patterns made by the different rates of mud drying, and attributed those patterns to hot and cold temperatures on the surface of the body.
What is the significance of thermography?
Thermography is a non-destructive testing method used to detect and measure small temperature differences to help find deterioration in assets and plant sites. Thermography can support the maintenance of industrial plants and equipment with its fast and cost-effective application.
What are the limitations of thermography?
Drawbacks or disadvantages of Thermal Imaging
➨Images are difficult to interpret in specific objects having erratic temperatures. ➨Accurate temperature measurements are hindered by differing emissivities and reflections from surfaces. ➨Thermal imaging cameras are not used for study of under water objects.
What are the types of thermography?
There are two basic types of thermography; passive thermography and active thermography.
