NightRise and image intensifier tubes
Inspired by the vision of nocturnal animals, night vision goggles (NVGs) operate on the principle of residual light amplification. Like the retina in an animal’s eye, the electronic components in the goggles capture the photons that come through the lens and convert them into electrons. These electrons are then accelerated under high voltage in a vacuum tube and projected onto a phosphor screen. The phosphor screen acts like a cathode-ray screen, retransmitting the signals in the form of images.
The type of tube depends on the type of device, and choosing the right tube — and above all the right architecture — is a crucial design decision. Thales’s world-class optro-mechanical know-how offers designers much more flexibility in the choice of tubes and lets them find the optimum combination of night vision performance and usability in the theatre of operations.
For new-generation night vision goggles, an 18 mm tube offers a number of key advantages over a 16 mm tube:
-
Stronger optical concentration
-
Higher resolution and MTF contrast
-
Better DRI performance
-
Lower sensitivity to cosmetic artefacts like black spots
On the other hand, conventional 18 mm tubes are heavier and less compact than their 16 mm counterparts, which could have a negative impact on the Size, Weight and Power (SwaP) performance of the night vision goggles. Glass-to-glass tubes, however, are significantly lighter than twisted-fibre tubes, making it possible to reduce the weight of the device, accommodate innovative architectures and offer a more compact optical design.
