Excellent illustration! Thank you Luiz! Aside from the combination of prisms - such a simple device!

Hello Luiz,
The rollover technique was not unknown to the west. Keith Melton shows in his book "Spycraft" an OTS (CIA) rollover camera from 1968.

Detlev:
This Jan III is a real scan camera but it works in a totally different principle.
Prints a readable but with uneven illumnation.

Hello Luiz,
the optical path is different, but it is the same principle: the film is moving while the document is scanned. When using a rollover camera you scan manually, Jan III does it automatically.
