PHOTONIS 3D IMAGE INTENSIFIER

Photonis is the world leader in the design and manufacturing of state-of-the-art image intensifier tubes for military, space, and commercial applications. Image intensifiers are devices that intensify or amplify low light level images from natural sources, such as starlight or moonlight, or from artificial sources such as street lights or infrared illuminators.

Good stuff. One of the better animations I've seen explaining how IITs work.

PSR sent me here

Your animation helped me the most to understand the matter. Good animation.

[@THEOGGUNSHOW]

Outstanding

[@MassaSnowshi]

This is awesome stuff.
Simple enough that a simple brained chimp like myself could understand.

[@markrichards7452]

You seemed to leave out the little wizard that lives in most other ITTs. Otherwise, good video!

[@JustAverageJeff]

So crazy you can just multiply the electrons, great animation thank you!

[@riflemanm16a2]

That part made no sense to me. From what I saw in another image, there is a current flowing through the channels which causes the electron to accelerate and collide with other atoms and knock off their electrons in a process called "electron avalanche". I don't fully understand it, but it sounds like fission but with electrons instead of nuclei.

@@riflemanm16a2 The MCP holes are angled 5-8 degrees. When an electron enters a channel, it impacts and several secondary electrons are emitted because the MCP has voltage applied to it. These impacts occur repeatedly based on the width of the hole. The final electron multiplication is between 1000-100,000x. Physically, the MCP is made from a bundle of drawn leaded glass fibres, bonded and sliced into a plate, then chemically etched and coated.

[@riflemanm16a2]

@@Tattlebot Thanks for the explanation. Makes more sense now.

[@dropclock.]

@@Tattlebot would 8 degrees increase the amount of bouncing therefore the multiplication of photons therefore meaning a brighter image? also would the concentration of channels increase resolution? also where did you learn this, I'm interested in manufacturing image intensifier tubes. although the tech for it might be extremely expensive to which I wouldn't be surprised.

[@Tattlebot]

​@@dropclock. The MCP bias angle ensures that the electron impacts at the channel entrance and also blocks light and ion feedback to the photocathode. Night vision tube resolution can be limited by the MCP, the twisted fiber bundle, or the phosphor particle size.

You can't multiply electrons without anything lol they have mass you can't create it like with some reflection lol they must be using some kind of battery or so😂😂
