Curved sensor

[Kenneth C Merrill]

It seems to me that designing a concave sensor would solve a few of the issues that accompany pushing the boundaries of lens performance. There wouldn't be a vignette for wide lenses at fast apertures (normally due to the angle of incidence of light on the pixels). Corner sharpness would probably be better. Less chromatic aberration?

it seems viewing technology is moving toward curved screens. Is there a reason it wouldn't work for sensors?

Is there reasons why it works for TV's?

It's been done, Don't I think does it, and it liws less sensor elements and a lower profile camera.

Your reason seems a little strange, you believe the science behind having a Curved Sensor would be to allow curved projection?

But, I remember reading about it and here is a links
DP Review Curved Sensor

the basics are that because of the design of a Lens, there is an Optical Element added to combat Petzval's Field Curvature, which I assume makes lenses slower and add other arbitrations. You can read the same article I read above.

Thinking that this will work with all the lenses you presently own is a mistake. Seems like, you would also need all new lenses, or at least need to do some major surgery on existing lenses, to allow them to be able to be used.

...with curved projection, I'd imagine it's the same tech being used as was when you would de-squeeze a anamorphic print, a lens in front of projected image. But, that's just an educated guess

The lens stack is carefully made to get rid of issues, thus a good lens has lots of elements to correct issues. So the curve gets rid of elements to do with this, and whatever elements that deal with issues those elements in introduce. However you should look at liquid lens. I don't know if curvature adds to performance to that, but of so, even better. One day hopefully somebody will do a descent camera combining those things. If Red had used this on the Scarlet Fixed, it probably would have all fitted in and worked.

I sure as hell don't want a curved screen. I mean, when we had curved screens, they were just TVs, and we sat far away from them, so it mattered not. But I want cinema screens and monitors etc. to remain flat. I don't think that a curved sensor exists for the sake of curved displays.
