Night Vision is the general term for the technology of image intensification. An Image Intensifier Tube (IIT) is incorporated within a Night Vision Device (NVD), providing an operator the capability to amplify the available ambient light. This amplification subsequently allows the Night Vision Device to operate in low-light.
Image Intensification operates by amplifying the available light to achieve better vision. An objective lens focuses available light (photons) on the photocathode of an Image Intensification Tube. The light energy causes electrons to be released from the cathode which are accelerated by an electric field to increase their speed (energy level).
Night Vision typically falls into three categories, that is, Night Vision Devices, Night Vision Modules and Night Vision Goggles.
Night Vision Devices are also commonly referred to as NVD’s, Night Vision Monoculars & Night Vision Scopes.
Examples of Night Vision configuration variations include, but aren’t limited to:
- Night Vision Goggles (NVG's)
Night Vision Devices can be operated as handheld, head-mounted or attached to cameras & camcorders for image gathering.
Night Vision Goggles are utilised for hands-free, low-light observation such as whilst driving or being utilised in an OP (Observation Point).
Night Vision Modules are used specifically for low-light, extremely high resolution image gathering, whilst utilising the dSLR body's native objective lens.
Rife within the Night Vision industry is Image Intensified Tube substitution. This is where a piece of kit is procured, such as a Night Vision Monocular, however the purchaser is unaware of which Image Intensifier Tube has been utilised in the kit, see: www.militaryandlaw.com.au/page/tube_substitution.html.
