Sinar /Winnek 8x10 3D Scanning Camera

[Trinar3D]

This is my camera - It was willed to me after the inventors death. Doug Winnek is well known in the history and development of Autostereoscopy - 3D with the unaided eye.
I worked with him, his wife and this camera and its predecessor, an 11x14 scanning camera, for 15 years in the Carmel Valley, CA.
Its a Sinar P 8x10 back and bellows with a Burke & James Lensboard with a Packard shutter. A 12 inch Kodak Ektar Commercial Lens. The Back and lens travel on a track, offset from each other according to the focus plane of the subject. A screen is imposed on the film during exposure, also travelling.
I am in the final stages of restoration and am ready to shoot soon. It produces amazingly detailed 3D images right out of the camera. I have done portaiture, architecture, landscape, product and computer graphics, including MRI in 3D with this camera.
Is anyone familiar with this process, or any large format 3D applications?
Thanks,
Harold

Sorry, pics & video removed. Here's the patent:

Bob Shrader was the engineer who built Doug's camera design.

Not a clue. Post some images; show us what it does. Might be interesting.

[Ben Syverson]

Yeah, I'm curious as well...

Thanks for your interest.
The images this camera produces require viewing in person with both eyes to perceive the stereo effect. I prefer to exhibit them as backlit transparencies, but can also be viewed as reflective prints. The Winnek camera belongs to a general family of 3D scanning cameras. A similar design, the "Bonnet camera" also moves during exposure, although it travels on an arc, creating distortion in background subjects with good 3D in the main subject. The Winnek Camera travels in a straight line, with true distortion free perspective from 3 ft to infinity.

That sounds really interesting. Can you post an image made by that technique?
A monitor is like a backlit image. Or do you need a lenticular lens to view them?
What I dont really understand is how does it prevent the image from smearing while the
camera moves?

3D prints have been made in the past called Vectographs. Dupont made a special film
for this application, for direct viewing (no colored glasses needed). A complicated process requiring precise registration.

[Trinar3D]

Actually Vectographs used the polarizing filter effect to isolate the left and right views, but needed to be viewed through polarizing glasses.

Can't you pls. post some images of what the camera does? Sounds incredibly interesting.
