Anyone considered using a fresnel lens/ mirror system?

Darius machines had three monitors lined up horizontally to form a single image. One of the monitor images was actually reflected off a mirror (a bit like Space Invaders) to enable the three images to be stitched together with no gaps showing.

I was thinking you could build a MAME based Darius machine that only used a single monitor. The game would be shown on the monitor with the image squashed up horizontally. A fresnel lens could then be used to expand the image horizontally so that it looked like you were seeing three monitors.

I have no idea why they would design the original that way.

I've actually seen one in an arcade and the design works really well. In a nutshell you get a lot more screen area to play with.

Oh, I mean, I understand what it's doing, but there are other less failure prone methods they could have used to get the same thing.  Keeping one monitor going is hard after a while... but three?  And then if they get out of alignment it's all messed up.

I guess the economics were different then. 20 years ago large CRT monitors were prohibitively expensive (ironically these days you can hardly give them away). That being said I wonder why they didn't go the Fresnel route instead.
