The thermal imaging camera and how it works
A thermal imaging camera records the intensity of radiation in the infrared part of the electromagnetic spectrum and converts it to a visible image.
The thermal imaging camera
Infrared energy coming from an object is focused by the optics onto an infrared detector. The detector sends the information to sensor electronics for image processing. The electronics translate the data coming from the detector into an image that can be viewed in the viewfinder or on a standard video monitor or LCD screen.
Infrared thermography is the art of transforming an infrared image into a radiometric one, which allows temperature values to be read from the image. So every pixel in the radiometric image is in fact a temperature measurement. In order to do this, complex algorithms are incorporated into the thermal imaging camera. This makes the thermal imaging camera a perfect tool for industrial applications.
12 things to consider before buying an Infrared Camera:
1. Buy an infrared camera with the highest detector resolution/image quality that your budget allows.
2. Need to present ndings to others? Find a system with a built-in visible-light camera outfitted with an illuminator lamp and a laser pointer.
3. Select a camera that delivers accurate and repeatable results.
4. Look for an IR camera that stores and outputs standard file formats that are broadly supported.
5. Consider the added value of an IR camera that links to Bluetooth-enabled T&M meters for assessing electrical load and moisture levels.
6. New Wi-Fi apps for mobile devices help streamline the sharing of thermal images and data; select a camera compatible with this leading technology.
7. Make sure you get a camera with the ergonomic features that make your job as easy as possible to match the way you like to work.
8. Thermal Image Enhancement and Picture-in-Picture (P-i-P) will allow you to combine thermal and visible-light images for generating reports that are easier to understand.
9. Not all reporting software products are created equal: Be sure to try out the product first to find the one that’s right for you.
10. Choose a thermal imager with a wide temperature range so you can measure ambient and high-temperature spots in the same image.
11. Look for cameras with a comprehensive, extended warranty program to protect your investment for the long haul.
12. Make sure your investment in an infrared camera is backed by a strong manufacturer who will provide ongoing technical support and training.
