Single lens, single camera 3D
 
I'd be pleased to forward a peer-reviewed medical paper on this technology we used in the 90s in minimally invasive surgery, typically with 4mm-10mm rigid endoscopes on live humans. Best application appeared to be nasal surgery because of the very close working distances. Now, we have two proof of concept 3D HD cameras (Dalsa) which are relatively portable and give the same, comfortable imaging we had in MIS.

Where can we find the information? Can you provide a link?

Like this:
Loreo Products - LOREO 3D Macro Lens in a Cap (Model 9006)

or anamorphic like Outboard 3D DV Lens?

Ah, yes, Loreo. That's what I use, too (as in this video). Alas, it results in a 16:9 video becoming an 8:9 video. It also forced to me to write my plug-in, just so I can edit the videos it makes.

I really wish Loreo made them 2:1 anamorphic, so I could get a full 16:9 stereoscopic video from it.

Link to medical paper on 3-D endoscopy
 
It is an old paper and International Telepresence became Isee3D, Inc.

Insects and spiders in 3D
 
When the I was not observing minimally invasive surgery procedures in 90s, I used a single rigid endoscope for capturing 3D of flies and spiders. A large spider excavating out the thorax of a crane fly shot at a range of a centimeter or less, is a sight to behold! Similarly, a mother spider with her spiderlings in a dense mat of threads in 2D, took on a whole new meaning in 3D. Aside from separating out the threads, 3D also allowed you to make a much greater 'connection' with the subject matter. The spiderlings almost seemed to have human, childlike movements! Bugs can be cute or unnerving, especially in 3D. Remember, the endoscopes shoot out light around the lens so lighting was not a big issue. The smallest 'scope we ever used was a point 9mm (0.9) retinal 'scope, but I never tried it on bugs.
