What Can You See with a Infrared Camera?

A infrared camera is a device that converts thermal energy (heat) into visible light to analyze a specific object or scene. The resulting images are called heatmaps and are analyzed through a process called thermography. Infrared cameras are complex devices that process captured images and display them on a screen. These images can be used for point-of-care diagnosis or processed by dedicated software for further evaluation, accuracy and reporting output. Thermal imaging cameras take temperature measurement to the next level; instead of getting numbers for temperatures, they get pictures that show differences in surface temperature.


1. What can a infrared camera see?


Visible light is what we see around us every day. It is the only part of the electromagnetic spectrum that we can see. Visible light occupies only a small area of the electromagnetic spectrum, while infrared radiation (IR) makes up a much larger percentage. If we want to see what's going on in other parts of the spectrum, we need specialized equipment. All objects absorb, reflect and even transmit energy at various levels. Different materials release heat or cold energy at different rates. It is this energy that can be detected by infrared devices and displayed as images.


2. Application and use of infrared camera


Originally developed for military use during the Korean War, infrared cameras have migrated to other fields and found many uses. Firefighters use them to see through smoke, find people and locate fire hot spots. Law enforcement uses the technology to manage surveillance activities, locate and apprehend suspects, investigate crime scenes, and conduct search and rescue operations. Powerline maintenance technicians locate overheated splices and components to eliminate potential failures. Where insulation has failed, building construction technicians can see heat leaks to increase the efficiency of cooling or heating. Physiological activities in humans and other warm-blooded animals, such as fever, can also be monitored by thermal imaging.


3. The function of infrared camera


The camera has a variety of user-selectable color palettes, such as black/white hot, iron red or iridescent. The black/white palette helps identify details on images, and the rainbow palette has the best thermal sensitivity to show temperature differences. Different color palettes can also be used for different scenarios: white heat and black heat modes are suitable for finding heat sources in the dark, suitable for outdoor scenes such as hunting and night vision; iron red and rainbow can show rich details and subtle temperature differences, suitable for industrial measurement. temperature, circuit maintenance and other industrial scenarios.
