... the mirror/prism configuration that can rotate an image fed into a camera by rotating one (or more) of its component mirrors?

Yes. Also (more prosaically) "image rotator".
That's it. Thanks.
Dove prism?

If you Google on that, you've got to wade through a whole bunch of software apps.
You can often greatly reduce the wading effort by entering "-compiler" or some other word that is most likely to occur in a software-related description. Then it (usually) ignores all hits with that word in there.
"Dove prisms have an interesting property that when they are rotated along their longitudinal axis, the transmitted image rotates at twice the rate of the prism. This property means they can rotate a beam of light by an arbitrary angle, making them useful in beam rotators, which have applications in fields such as interferometry, astronomy, and pattern recognition."
Edmund scientific had them listed in their catalog last Millennium. :-)
