I impressed from telescopes.
They have big mirrors and a small mirror at the focus , they are two axis symetrical , i mean verticaly and horizontaly symetric and curved.
What happens if I use a cylinderical mirror which made from curved stainless steel plate as the big mirror .
A there can be film at the focus of the big mirror ?
B or there can be a small cut cylinder stainless pipe as a secondary mirror which focuses the light through a hall at the big mirror on to the film at behind of big mirror.
What kind of image we get from horizontaly curved lens or mirror ?
Can it be computer corrected ?
I asked few experts offline but they said they did not know the answer.
