How do ballistic proving grounds track objects that are moving beyond the ability of the eye to follow? They use specialized cameras that can take upwards of 25 million frames per second and use mirrors to keep the projectiles in the middle of the frame.
I have a friend who uses these high speed cameras at work.

This guys bio is all about high speed photography

I was surprise to see them fire the artillery shell without a fuse. The lifting eye didn’t seem to affect flight stability.
This is cool technology. I have seen it used for vibration analysis when accelerometers could not be used due to the high temperature of the component. The software actually analyses the film, measures the displacement of the part over time, and then calculate the velocity and acceleration.
No word yet when a camera can track the rate of dollars flowing out of Washington.
A similar technology is used in laser printers. The laser diode remains stationary while a hexagonal mirror spins and reflects the laser light across the photoconductive drum. I’ve been working on laser printers for over ten years, and it still amazes me how it works.
Mirrors are the only way that I’m able to comb my hair….
It’s truly amazing what can be done in certain fields by brilliant people. But we still can’t find people smart enough to give us simple tax plan.
Phucking amazing!
I’ve found myself just hating mirrors a little more every year.
Uncle Fester is really upping his “Science” game!

Papa Flash was a lovely gentlemam. The autographed copy of ‘Moments of Vision’ sits in it’s place of honor upon our bookshelf, dust free.
