The smallest Baird Televisor?
My local garage is selling laser devices that project
a straight line for just under a fiver. I wonder if these devices (with the lens removed so that they just produce a single spot) could be modulated to be the light source in a Baird Televisor? Also, I wonder what is the smallest such Televisor that has been produced? |

No it won't
How will you bend the beam? Do you propose that people look straight at it? You would need to get the beam just the right width.

I'll admit I dont know Baird and the Televisor stuff. (Beyond the
"father of TV "stuff) Lasers though are can be pulse width modulated (PWM) to pseudo change the spot intensity. In a air comms environment they are pulsed at some "carrier" frequency and data then sits on top of that. At the RX end they have a filter at the "carrier" frequency so you dont get noise etc from other light sources. Making a picture? Had a brief think about bending light but that physics is kind of missing in my brain! I think if you used a rotating mirror array on two axis in front of the beam you might get something acceptable, be a real cow to manufacture though. Syncing would be reasonably easy (assuming a standard TV picture signal) but I think the spot would be a bit large unless you wall projected it. Colour wouldnt work BTW as the (laser) spot will be one freq only. This means any filtering or coloured mirrors wont work. Those laser pointers sound like a nice cheap way to experiment with some short haul data comms as well.

Played with it last night.
Powered as it is by AAA cells, it seems to have a greater power, and a greater reserve of power, than those laserpointers powered by watch batteries. Allowing for the lens that is used to produce the straight line beam, the spot from the end was easily picked out on a gravestone 1/4 mile away, thus suggesting that a tight beam is being produced. As these beasties come in a mounting that already has facilities for screw fixing, perhaps there is potential capability for optical communications?

Your deep-seated motivation to pooh-pooh just serves to

There are many things which have "been done" and yet which you do. (Apart from a Morse Code test that had "been done" by otherwise-unqualified self-taught 14-year-olds). HF Communication had "been done" by thousands, long before you purchased all the Cheque-Book (CB) rigs that you boast about. I don't think that I have ever been "interesed", whatever that may mean.

Well, you're the expert in behaving like that, and as you
practised it for over 20 years, it probably accounts for it being uppermost in your mind. How come you never managed to pass a 12 WPM Morse Test targetted at 14-year-olds in all that time? Are you, perhaps, too lazy or too stupid, or both? How come your objection to a Morse Code exam being used as a filter to control access to HF suddenly disappeared when a test down at your level, ie, targetted at 6-year-olds, came along?

What is the efficiency of a laser device like nowadays?
I went to a 3D TV IEEE demo back in the 1970's where the device looked like a TV but had "depth". Kind of like those kids puppet theatres! The big thing I remember at the time was the huge power consumption (1000-2000W?) needed to produce even a moderately lit picture. It was said at the time that the appliance would probably never be marketed as a 3DTV in every house would flatten the electricity supply system every time a football/crickrt match was on! I cant quite remember the physics or name behind the 3D technique. Some kind of inteference pattern generation maybe. The name escapes me...

UK record, as of a couple of years back at least, was something like 75km. There is project in the latest RSGB handbook (if you are interesed I'll look up the page, I noticed the article but haven't read the detail). The current UK laser record is around 73km I believe... held by G0MFR and G8LSD. They used standard low power red laser diodes of the kind found in the pointers. Barry,G8AGN, Gordon G0EWN and myself (all in Sheffield) are also experimenting on these lines have done a 45km path so far... using cw. We have some LOS paths up here in the North up to 136km so we're hoping to better the record one day soon :-) Peter, G3PHO |
