- I've done a bit more research since I posted the original article (by
- the way, thanks to Robert and Anthony for their replies). The only
- reference I could find was in the 1986 Television Engineering
- Handbook, which cited a paper by T. Taneda, et. al. in something
- called the SID 1973 Symposium Digest Technical Papers, vol. 4, May
- 1973, pp. 86-87. The TEH included a diagram of it - it used rotating
- mirrors and prisms, that sort of thing. Still, I was amazed that it
- had been done in '73.
-
- It seems that one could make an improvement on this system by
- using more modern laser-deflection techniques. I remember seeing
- a setup at SIGGRAPH '90 which used some sort of crystalline
- substance which changed its index of refraction when a voltage was
- applied. I'll have to look into it some more to see whether this would
- be feasible for use in TVs (they were using it for something else).
-
- Anyway, the reason for all of this is that I was thinking: if I wanted
- to start an American company to produce consumer video
- electronics, what product could I start with? Not VCRs, or
- camcorders, for sure. It seems that TVs which employed some sort
- of superior imaging technology would be a good bet, since it doesn't
- matter whats on the inside of a TV so long as the picture looks good
- and it runs off NTSC signals. Possible entrepreneurial idea?
