Hi Steve, brililant.
This reminds me of when I was a schoolboy I found a design in a construction book for a flying spot scanner. It had a photo-multiplier tube to pickup the image from a modified TV - our old Decca dual standard with sliding doors iirc.
I have lost the book and no longer have the chassis withthe electronics. I think there about six valves. Has anybody seen a book with a flying spot scanner design, I'd love to see it again.
btw, it never worked very well at all but you could make out a hand in front of the scanning TV.
Kind regards, David.
