A lot of cases exist where review of the system is required without contact, and this is commonplace. Infrared Inspection is the method of inspection of a system or materials with the use of ultraviolet sensors. This is the preferred method when it comes to inspection of places that are not accessible to access.
This type of inspection is not intrusive, which means that the process will not affect the state of the system in any way. Ultraviolet technology has gained popularity over other methods employed earlier such as ultrasound examination and radio graphic testing as it is safer, much faster and does not interfere with the system in any way.
The review process, also known as thermography, can be either of the passive or active form. Passive thermography refers to cases in which the target of interest is at a different temperature from the background. Active thermography relates to the use of a source of power to create a contrast in temperature. Power may be used from optical devices or mechanical stimulation.
Every item in nature emits some infrared energy. Thermal cameras are used to capture and convert the ultraviolet energy into a visible image. These cameras passively identify objects without requiring a light source. However, cameras are not used for objects that are frigid as they do not detect such low temperatures. An active energy source may also be used in conjunction with these thermal cameras.
Advantages that thermography provide includes inspection of hazardous and other inaccessible areas, ability to detect objects in the dark, ability to capture moving images and is also used in medical applications. Other areas where thermography is used include thermal mapping, night vision, surveillance and any other form of non-destructive testing.
However, there are some limitations of ultraviolet thermography. The cost of this technology comes out to be pretty high. Quality cameras will be required for accurate measurements, and these are usually expensive. The accuracy of the camera primarily determines the accuracy of imaging. Poor grade cameras will lead to mostly inaccurate imagery with incorrect measurements of temperature.
Some other fallacies to this process are external factors. Temperature is something that can change very rapidly and due to a number of reasons. Also, the area surrounding the target may contain other bodies that may also be reflecting or emitting waves themselves. Other external factors may include sunshine, rain and the climate of the area.
Despite its flaws, thermal imaging has been beneficial to industries across many applications. Ultraviolet Inspection is one of the prime methods employed for non-destructive testing and non-contact inspection of materials and is also very safe and quick. It has found a variety of uses in night vision, surveillance, medical inspection, process control and in various other fields including chemistry and research. However, the accuracy and cost of the process remains a concern. Technological advancements which have happened so rapidly, have already led to a number of processes being replaced with ultraviolet detection and we can definitely expect expenses to go down in the future as infrared keeps expanding its sphere of applications.
