hypergonar
n.— «Chrétien’s “hypergonar” adapters made use of an optical trick called anamorphosis, whereby a curved lens placed in front of an ordinary camera could squeeze a large field of vision into the frame. Another lens, affixed to the projector, would reverse the process, spreading out the image onto an extended screen.» —“Why It’s a Wide Wide Wide Wide Screen” by A.O.
