One Million FPS Slo-Mo Bullet Impact Video

Cool to see Physics in action

Unrelated, but speaking of high speed...

In my lab we have a multiphoton microscope used for high resolution cell imaging. It uses a pulsed infrared laser which has a pulse width of about 20 femtoseconds (0.000000000000020 sec.) and a peak power of ~ 100 kilowatts.

I can honestly say, that's the first time I've ever heard of the word, Femtosecond. Let alone see it used in a sentence.

I can't edit the title of the thread. With the new information, I feel comfortable saying the F P S would mean Frames Per Second, not feet per second, as I first thought.

Still,it sounds like a lot frames per second.

Indeed. High speed X-ray. Exposure times in the tens of nanoseconds and frame rates above 1 million frames / second.

Maybe an exposure in 1,000,000th of a second.

But I doubt a frame rate of 1,000,000 PS.

But no matter. Its a cool video.

I guess anything's possible these days.
Who comes up with these measurements anyway?





A femtosecond is the SI unit of time equal to 10-15 of a second. That is one quadrillionth, or one billionth of one millionth of a second. For context, a femtosecond is to a second, what a second is to about 420 million years. To give another example, one femtosecond compared to one second is like the diameter of a human hair relative to the distance between the earth and moon

What, is this from the 1940's or something? Could you ask them to do it over in color?

Must be your monitor.

Maybe "color" can't record fast enough? I don't know.

This high-speed technology does indeed exist. It looks like this camera, or something similar was used in those ballistics test videos.

And this is just some of the more readily available stuff.....

Interesting article.

Wonder what that camera will set ya back?

[beenthere]

I want one.

No idea what I would use it for after a month or so. But it would be cool for a month.

they have technology up to 25 million fps

that video is pretty neat

Yea. And all that could be outdated by the end of next year.
