Just arrived at work. Brand new VEO 710S. 7 gigapixels per second, 1 megapixel monochrome sensor, $57k. Typically we use EOS mounts, but this has a C-mount to couple a fiberscope to. AMA I guess.

Here’s the analog fiber scope in place. $70k on a tripod. Better not trip!

And obligatory fiber scope Phantom selfie!

Will you get fired if you drop it? Also, where’s the lens?

I dropped one a few years ago and racked up a pretty expensive repair bill and didn’t get fired. So probably not but I don’t want to make a habit of it. We’re actually using a fiber scope with this guy. I’ll update with a photo of that when I get it attached.

1 million frame per second... at 64x8 pixels? What is there to see with only 512 pixels in monochrome?

still, pretty sweet camera!

What is it going to be used for?

Here’s an F-mount lens on it using an adapter. That entire black plate can be removed and the C-mount swapped for F, PL or EOS. We use EOS on our other Phantoms because Canon has been open with their electronics - we can control focus and aperture remotely while with Nikon it is all still manual at the lens.

Kinja'd!!!

Woo! Is that a Nikon 50mm f/1.2?

Watching something small go very fast. I do R&D for a defense contractor. So watching bullets and bomb fragments - that sort of thing.

Yes. We have damn near a dozen of them laying around. A lot of the stuff we do required lots of light but not much depth of field so they are almost a default to grab.

Well on the other end it’s 7,500 frames per second at 720p. Typically we run it somewhere in the middle. Measuring the speed and path of bullets and blast fragments works fine in monochrome at 30-50 kHz. At 64x8 you’re typically watching shock waves from a blast to determine the strength of the blast. Using a shadowgraph or Schlieren system will make the shock look like a vertical black line on a white background and then we track it’s postition vs. time at 500 kHz or more.

ooooooh! plz gib?

I don’t konw what a Schlieren system is, but that whole setup sounds awesome. Do ballistics and projectiles involve a fair bit of your use for this camera?

In my former workplace we had a camera set for seeing droplets coming out from a common rail diesel injector. It used fan shaped laser to light up the droplets and took the pictures from 90 degree angle from the laser’s direction. It could take two pictures in very short time but it couldn’t take any more without rather long data transfer pause.

I bet that camera could film the entire injection phase.

It can. Our organization has another department that does fuels research and one of our guys has done some experiments for them using a continuous laser sheet and a similar Phantom to do time resolved droplet measurements from injectors.

It’s been a fun ride. I’m leaving in about a month to go work for another company where I’ll be looking at very small things instead. I’m going to miss this stuff, but I should have some fun toys at the new job too.

Good luck at the new job!

Our use yes. We primarily develop armor so they get a lot of use in development tests. But we do also get into fluid flow, aerosols, crash tests and things like that. Industry-wide ballistics is a big portion of sales for these cameras, but Hollywood and sports broadcasting also buy a lot of the color models. We stick to monochrome because without the Bayer filter over the sensor we get a little more light. Most of our exposures are around 1 microsecond (1/1,000,000 s in camera dial terms) so we need all the light we can get. Schlieren is a method that uses lenses to make density changes in air visible. In very simple terms think of the mirage that you see coming off of a hot street surface and turning those waves into a grayscale image: https://en.m.wikipedia.org/wiki/Schlieren

That sounds awesomely fascinating. I’d kill to be a fly on the wall in that lab for a day.

Haha if you were local they probably wouldn’t miss it if you borrowed for a while. My favorite lens to play with here is probably the 200mm f/4 macro. It lets you get 1:1 magnification from darn near a foot away from the subject which never gets old.

Yeah there’s days I can’t believe I actually get paid to do this. But like most jobs there’s a lot of behind the scenes stuff that can be a drag.

Answered the main question I was going to ask, that is, why you use EOS lenses.

I used to work for a company where we developed/built high end surveillance cameras for military and LE applications. I can’t recall the mount type, but I know it wasn’t a typical SLR lens mount. We used ridiculously expensive lenses with either a command set or some form of feedback for lens control (either higher-quality resistors or, preferably, optical encoders). I worked in software and firmware, so I mainly dealt with motion control, UI, and interfacing with a variety of other systems...

I did a crap ton of ballistics experiments in a past life. We never had the camera gear, though. We used witness plates. And blew up cars...

Sounds fun we use a lot of witness plates as well!

Cool! We used 4x8 plywood sheets held up in a circle around the blast. They all fell down...

So... all I can really say about that is that the large Gov’t facilities in New Mexico are hiring at a pretty good pace right now. If you’ve got a resume together you can probably find some pretty interesting job descriptions to apply to and maybe you’ll end up following me out there!

I love New Mexico. Convincing the wife to love New Mexico, though...

I so would, though. I need a year to finish my Master’s degree, though.
