INTRODUCTION – NIGHT VISION
• ‘Night Vision’ literally means ‘to see in low-light conditions’
• The technology which allows the people to see clearly in a dark environment is
called as ‘Night Vision Technology’
3
GENERATION 0
• Required
invisible infrared
light
GENERATION 1
• Three image
intensifier tubes
were used
GENERATION 2
• Used Image
Intensification
technique
GENERATION 3
• Evolution of
micro channel
plate
GENERATION 4
• ‘Filmless and
Gated’ image
intensifiers
GENERATIONS OF NIGHT VISION
4
Image Enhancement
o Collects tiny amounts of light,
including the lower portion of the
infrared light spectrum and
amplifies it
o The gathered light is sent to the
image-intensifier tube
Thermal Imaging
o Operates by capturing the
upper portion of the infrared
light spectrum
o Focused light is scanned by a
phased array of infrared-
detector elements

The thermal image is converted first by the sensor into electrical
signals.
The higher the temperature, the higher the electrical signal and
the whiter the pixel will be shown.
From a physical standpoint, this represents electromagnetic
waves with a wavelength of 8 μm to 15 μm. This long-wave
infrared radiation is known as Far Infrared (FIR).
Essentially, FIR systems consist of an optical element, a thermal
imaging camera, a control unit and a display.
OPERATION PRINCIPLES
12
It has improved the vision conditions of dusk and darkness.
There is no dazzling by head lights of the oncoming vehicles.
It ensures the highlighting of illuminated, heat-emitting objects
as pedestrian, cyclists, etc.
It illuminates the bends/curves.
It has superior image quality.
It provides an uninterrupted image.
ADVANTAGES OF PROPOSED
SYSTEM
13
The advancement of this technology along with the GPS(Global
Positioning System) Navigation will bring about the advent of
driverless vehicle.
Effective night vision could be the key parameter in such
vehicles.
This technology will probably be applied in hidden object
detection and wildlife observations.
