3. 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’

4. 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

5. 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

12.  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

13.  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

14.  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.
