Question

who know that...???
i want to build Night vision like "Infrared Camera" . and my Knowledge and information is low , but i like build...
who know that how i should start ?? thanks :)

Answer 1

To compose an item for night vision may require that you begin to study optics.

Answer 2

True night vision is typically achieved by viewing light in the short wave infra red wavelength around 1 - 2 microns.

Typical cameras have sensors based on silicon CCD or CMOS technology. These sensors are not sensistive to light in that wavelength and hence are not suitable for 'night vision'.

They ARE slightly more sensitive to the red end of the visible spectrum (700nm +) and hence are used with IR lighting for security stuff, but this is not true night vision.

I believe the sensors are very expensive - you would probably need to develop your own camera for this purpose

Answer 3

Also depending on the wavelength that you wish to view may require special optics ie, lenses made from materials that are transparent to IR radiation.
