Introduction to Infrared Imaging
Infrared (IR) imaging is a technology that captures and displays images using infrared radiation, a form of electromagnetic radiation that is invisible to the human eye. It leverages the fact that all objects emit infrared radiation, with the amount of radiation emitted being directly proportional to the object’s temperature.
Infrared Radiation and its Properties
Infrared radiation, a part of the electromagnetic spectrum, lies between visible light and microwaves. It encompasses a wide range of wavelengths, typically classified into near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR). Each region has unique properties and applications.
Infrared Cameras and their Working Principles
Infrared cameras are designed to detect and measure infrared radiation. They work by converting the infrared radiation into an electrical signal that is then processed and displayed as an image.
Types of Infrared Cameras
