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 examination is entirely safe as it does not alter the target system and also does not disturb its functioning. Prior to this, other methods including ultrasound techniques and radiology methods were used. Proving to be safer, faster and more accurate, ultraviolet technology soon replaced these traditional systems which would also interfere with the target system earlier.
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.
Thus, infrared thermal imaging can be active or passive. When the material to be studied is at a different temperature than its background, an external energy source is not needed for imaging purposes, and this constitutes the passive form. Active type requires the use of an energy source to create a temperature difference. This energy can be light energy or mechanical wave energy.
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.
This process however also exhibits some considerable shortfalls. Infrared is considered to be expensive, and quality thermal and good ultraviolet cameras come at a steep cost. Being integral to the accuracy of results, a poor camera will yield poor results. Discrepancies will exist in the measurements in such cases, and this must be avoided.
Another problem that the infrared process faces is natural and other external causes which lie largely beyond its control. Temperature changes are rapid and frequent and can be caused by very different reasons. Also, other bodies around the target to be inspected may emit waves of their own or reflect other waves. The climate also plays a part in the imaging process as also does the weather.
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.
