I watched this video in a dark room and I could still see it, well done 👍
@halo3soap114
Yes finally! I was the one who suggested this video. Thank you so much for making this!

We do not tint the light green, it is the property of the scintillator light (or rather was, since nowadays different scintillators are used). Also the human eye is actually more sensitive to light at about 507 nm when in dark (using rod cells instead of cone cells). Yes, we see the color green the most, but that is for colorful image. With monochrome image, it is more useful to use the said 507 nm light. Great video though, love it!

Thermal imaging and its neighbours are fascinating. I worked many years for FLIR as a service engineer before I retired but I'm still nerdy about it lol
@Keith-t3k
For some reason I feel hungry after watching this.
@Geyrel
Great video overall, just some things to note: 14:57 the battery pack for the for the PSQ-20 goes on the back of the helmet, not the hip - you can see it in the image. This helps to provide counterweight on the helmet among other things. Analog intensifier technology is likely not going to go away anytime soon due to how energy efficient it is - as an example, a PVS-14 running off a single AA battery can run for 40-50 hours, something that current digital night vision technology can’t match. Very useful for extended field operations etc

Our company worked with IsquaredTs early on. It is not the sensitivity which is the problem, it is the "dynamic range" of and amplifying devices. When used in practice, the "bloooooming" effect lasted so long, that the recovery interval became the limiting factor. In actual fire fights they became unusable, and it was easier to just look out with ordinary eyeballs. The attack and recovery problem still exists today. Modern cellphones have much better speeds, but only at the expense of sensitivity. This is a fundamental physics issue, and cannot be undone.

The microchannel plates developed for image intensifiers are now used in a variety of scientific instruments to intensify single electrons when used to measure electrons produced when material is irradiated with Xrays. They are often backed with 2 dimensional delay line detectors rather than a phodphor scintillator. With this you can count single electron events and then also get a position of where the event happened. Coupled with an electrostatic energy analyser you can often measure the kinetic energy of the electron and the angle from which it was emitted from the sample. This is the case for angle resolved photelectron spectroscopy ARPES. This is one of the foremost techniques for measuring the band structure of materials and is pretty much the only way of checking the quantim mechanical calculations used to model the electronic characteristics of new materials for new semiconductors.

This is awesome, never thought I’d see you do a video like this. Analog night vision is pretty incredible stuff.
@gregebert5544
I have a gen-1 NV monocular, and despite being "old technology", it really does an amazing job making objects visible in low light. It was a blast using it for night-time paintball games.
@arjovenzia
With all the food analogy, really missed the opportunity to mention cut rock candy, which is very similar to the 2 draw process. An image is built up using sausages of colored candy on quite a large scale, and then stretched repeatedly, forming a rod of sugar made up of all the colored bits, which when cut has a tiny, detailed colorful pattern or picture inside it.
@alec3107
Hell yes! I used to use nvgs all the time in the army. Never thought you'd make content about them
@SasquatchsCousin33
That stock image of salami at 10:08. So helpful 😅
@MrSupro
My father ran the first field evaluation of the starlight scope for helicopter use in the U.S. army in the 60’s. He was an first Lt and an engineer. He also performed the first motion picture Kerlian theory photography using it.
@peyton_uwu
As somebody who subscribes to quite a few "tactical" channels, I saw a pair of nods in the thumbnail and just kept scrolling past... but I immediately did a double take and clicked on the video when I saw your thumbnail title design and realized it was made by your channel xD
@raulkaap
The double draw method reminds me of how they make boiled candy with images inside.
@SmokeyWire56
I have a Philo Farnsworth gen zero tube. I used an ebay tazer exciter to power it. I used pieces of stainless exhaust welded together for a handle and a holder for it. I had to use 700meg ohms of resistance to drop it from 15,000 to 900 volts for the grids. And I had to buy lenses. It works good enough to see around with an IR light.

Time for a nightraid on the fridge.

As an mass spectrometrist who uses and handles MCPs quite often, I love this topic!!
