Thermal Imaging

Thermal Imaging – which is also referred to as TIC (Thermal Imaging Camera) & ‘Infrared Cameras’ are typically utilised within Defence, Law Enforcement & Fire Fighting scenarios where the end-user is required to operate in very-low to no-light lighting conditions. Unlike Night Vision that amplifies existing ambient light by the use of an Image Intensifier Tube contained within a Night Vision Device, Thermal Imaging utilises a Thermal Core that detects the heat signature of the target.

A Thermal Imaging Device detects the infrared radiation emitted by the object, thus creating an electronic Image. Since Thermal Imagers don’t rely on ambient light like Night Vision, the Thermal Imager is totally ambient light independent. Thermal Imager’s utilise the detection of the target’s heat signature… Thermal Imaging allows detection through fog, haze & smoke.

With Thermal Imaging, targets stand out as they’re warmer or colder than the background they are viewed against (referred to as a thermal signature or footprint). This contrast is the ‘thermal image’ displayed on a display. Thermal Imaging technology falls into two categories –

  • Uncool detectors - are typically either temperature stabilised (at room temperature) or unstabilised
  • Cryogenically cooled detectors - using cryogenic cooling to very cold temperatures (below 200K)

Unlike Night Vision which has the characteristic ‘green’ image, Thermal Imaging is typically black & white or white & black when the polarity is reversed (although some kit utilise software to provide colour images, allowing easier differentiation of the different temperatures variances).

Thermal Imaging operates predominantly in 2 wavelength bands –
* Mid-infrared (mid-IR) - mid-IR has wavelengths going from 1.3μm to 8μm
* Thermal-infrared (thermal-IR) - has wavelengths going from 8μm to over 14μm

-Types of surveillance Thermal Imaging variations include, but are not limited to:

- Thermal Imaging Monoculars
PNP-MTHD Miniature Thermal Imaging Monocular
*   PNP-MTHDE Miniature Thermal Imaging Monocular with 32GB DVR Recording

- Thermal Imaging Cameras
*   'Mini TIU' Thermal CCTV Camera
