Thermography is mainly used in an infrared measuring instrument like an infrared camera, to detect and measure the thermal energy releasing from an object. Thermography is commonly used in industry for predictive protection, condition measurement, quality assurance, and forensic inquiry of electrical, mechanical and structural systems. Thermography is used in non-contact were it uses remote sensing, maintain the user out of danger and does not interrupt ahead or affect the object at all.
It is used as two dimensional were the Assessment among areas of the object is possible. The image allows for outstanding indication of the object and Thermal patterns can be imagining for analysis. Thermographies used in real time were it allows very fast scanning of fixed objects. It enables to capture of fast moving objective. And it allows capturing of fast changing thermal patterns. Some of the disadvantages of thermography are like Due to the low quantity of thermal cameras; quality cameras often have a high price range. When we use thermography we can only able to directly sense the surface temperatures
