Wow that must be hard to for the engineers to make that invention at that time.
-
Still at that time the idea was genius.

What you describe is the mirror screw system that you can see on my web site at the appropriate page.

there is a helix of rectangular metal bars alligned like a spiral. as the helix spins each bar is in a slightly different position to the viewer, so that as they move the image is scanning an x coordinate and a y coordinate, like a graph.now the light hitting the spiral corresponds to the coordinate on the spiral as it moves so that as it spins really fast,there seems to be an image formed and then a picture is created!the camera can also use a helix shape that makes the image at that coordinate
-
This is an interesting idea, LOL!

Well, normal CRT tube TVs, the kind used from the 1930s into the 2000s, use a big glass electronic tube to display what's basically a grid of electronic spots that can be turned on or off in various ways.
Mechanical TVs like this use a spinning disc with holes cut in it and a light behind it to display images. I can't really describe it better, as I find it a bit confusing myself.

I don't get this? What is this? Can someone explain this to me? I am really interested in it.

You should check the NBTV web site in uk. They sell some part for mechanical TV such as scanning disc, electronics and so on..They have some kit available also.
