How Does Thermal Imaging Work
HOW DOES THERMAL IMAGING WORK?
Thermal Imaging amplifies infrared heat radiating off objects and assigns the varying range of heat different shades of color through its onboard processor. This allows you to easily compare / contrast varying objects, animals and other heat signatures. Due to the variances in heat, you can have shades varying in color, as well as shades in a greyscale hue.
The main aspects to focus on with Thermal is the Resolution and the Hertz of the unit. Resolution deals with how many pixels are shown in each area within the picture. Since Thermal uses internalized processors and cores, it is very comparable to other electronics that offer you high resolution images. The higher the Resolution on a Thermal device the better the clarity and quality of the picture.
Hertz refers to how quickly an image/picture refreshes per second. The higher the number of Hertz the smoother an image appears as you scan a horizon or field.
Thermal has a very practical element to using in the field, particularly, there is no hiding from thermal. You can track where animals have been and see through brush to where they are hiding. Locating blood paths, or even downed animals with thermal is exceedingly easy, given that the animals heat signatures can be visible for up to several hours through a thermal device.
Thermal offers significant advantages in the Law Enforcement and Protection markets as well. Particularly in viewing hidden objects or persons, but also in determining amount of heat that is radiating from tires, engines or even people. Several Thermal options come with on-board recording, allowing you to take image and video, as well as GPS and WiFi enabled. Thermals can come in a monocular, goggle or weapons mountable device.
