Multi-functional handheld thermal binocular is always composed of two HD optical channels. The built-in location module, digital magnetic compass, and laser rangefinder can quickly and accurately perform its own and target locator, and the target information acquisition and upload. It has small size and low power consumption and is adaptive to various complex climates and environments.
As is known to us, there are two types of technology used in night vision goggles - image enhancement and thermal imaging. Binocular night vision goggle often integrates the two technologies together for better night vision performance. Image enhancement collects all the available light and amplifies them to make images easier to see. Thermal imaging capture infrared light that is invisible to human eyes which are emitted by the target the and the surroundings and form thermal images. Then after the processing of the integration algorithms, the enhanced visible-light image is fused with the thermal image to form a new image that inherits the advantages of both technologies.
Monocular is usually smaller and lighter than binoculars. Monocular is more convenient while moving frequently or continuously for it can be picked out and put back quickly. But it is less comfortable to use monocular to observe and trace the target, because you have to close the other eye. Binoculars is much more comfortable for long-time operation and observation, because you can use both eyes at the same time to get rid of eye fatigue and related headaches. But when it comes to size and weight, binocular is big, heavy, and tiring to be handheld for a long time.
