Thermal Imaging

Thermal imaging cameras, also called infrared cameras, detect the heat given off by an

object or person.

Everything we encounter gives off thermal energy. The hotter the object, the more

thermal energy it emits. This emitted thermal energy is called a “heat signature.” When

objects have different heat signatures, they are displayed in different colors, which make

it easy and quick to detect warm-blooded animals (including people) against cooler

surroundings.

Thermal imaging cameras have lenses, just like visible light cameras. But in the case of

thermal detection, the lenses focus waves from infrared energy onto an infrared sensor

array. Thousands of sensors on the array convert the infrared energy into electrical signals,

which create a video image. The infrared camera measures and displays a “thermal profile”

of objects in relation to the temperature of any surrounding objects.

Thermal imaging technology also allows users to detect targets by cutting through snow,

dust, smoke, fog, haze, and other atmospheric obscurants.

Armasight is convinced that its latest Thermal Imaging product line represents the most

sophisticated devices available on the market to hunters, SWAT Teams, and the Military

today, based on their superior price-to-performance value.

Digital Night Vision

Digital Night Vision is a fairly new technology that was introduced to the market within

the last decade. Similar to other passive night vision devices, Digital NV allows users to

view images in near-total darkness. The two main benefits of Digital Night Vision include

an ability to work during daytime or nighttime without risking damage to the device,

as well as real-time High Resolution Recording Capabilities in standard North American

NTSC video format or European PAL video format. However, recording capability is not

available on all models.

In terms of performance, some higher-end Digital NV systems can be compared to Gen 2

NVD, while the majority of low-end systems can are comparable to Gen 1. Use of powerful

IR Illuminators such, as the Armasight IR810W, drastically increases performance and

viewing distances of Digital Night Vision Devices.

Digital Night Vision technology is very different from conventional I

night vision. The

light enters the device through an objective lens, after which it is processed through a

highly sensitive, charged coupling device (CCD), and then sent to a Liquid Crystal Display

(LCD) where the image is displayed.
