There is a circular "imager" used for small endoscopes. I seem to remember it
uses a dual fibre that is rapidly spun in a spiral, to scan the image. One
fibre illuminates and the other recieves the light. It is a while since I saw
the paper...
I think one of the swallowable pill cameras may actually produce circular
images although the sensor may really be rectangular!
There was a circular medical imager developed at Stanford as part of a student
Phd research project, which also produces images not on a rectangular grid.

Wow! Not a single comment on the circular sensor. Joke or not I
thought it would draw at least some response from this crowd.
