Often, there exists an electrical fault in a wall or in a system that is inaccessible but needs to be inspected at top priority. Infrared Inspection refers to the process of the testing of electrical systems, materials or parts, otherwise not easily accessible with the help of ultraviolet sensors. This process allows for non-destructive testing of various items and systems.
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.
By law, any and every element radiates infrared waves unless at temperatures of absolute zero. There exist cameras of the thermal type and sensors which capture this wave energy and create an image out of it. Light need not be required for this process. This is termed as passive imaging. Active imaging is the other case in which an external energy source is required. At temperatures lower than minus fifty degrees Celsius, these cameras and sensors fail to detect changes and need to be aided by other instruments in order to function.
If the target exists at a temperature difference from its surroundings, passive processes can be employed. Often, however, an external light energy or external mechanical oscillations need to be provided to the target for creating the contrast, and this constitutes the active process of imaging. Imaging in this case is of the thermal type where the change in temperature is converted to an image.
Thermal imagery process has many benefits. It is a very precise process, and dangerous systems and otherwise inaccessible regions can be quickly covered with this process. It can be used in dark and also for capturing objects in motion. It has many uses in applications of thermal mapping, infrared and night cameras, surveillance measures, medical and health care and many other inspection forms wherein the target cannot be disturbed or come into contact with.
Infrared thermal control, however, has drawbacks. The technology is pretty expensive, and good thermal cameras come at a high price. They are an integral part of the measurement and compromising on camera quality will lead to poorer results of the investigation with captured values having a lot of inconsistencies in temperature measurements.
Other shortcomings that this process faces are that the temperature may behave erratically, and measurements are also affected by reflections and other ray emissions. Thermography can only measure temperatures at the surface of bodies and is also largely dependent on other external conditions.
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.
