  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

The cost of 4k laser projection. Speculation Red Laser Price.

Just read the article, stone age, these guys understand little (/nothing) of what they are actually seeing.
 
Amendment 11/04/12: corrected word "nonexistent" to "nonexistence". Auto spellchecker error.

lol that would explain why i could read it.... Your a smart guy Wayne personally i would not worry how other people read your storys the gibberish rantings of mad men are usually the best ones and more commonly remembered throughout history...Now stop hurting my brain please winter is coming and i have wood to chop and need to concentrate. :)
 
Your in tassie ;), great place, a bit cold for me
 
Still nothing, but from the lcos talk, I guess it is nowhere near as advanced as what I have.

Sounds like expensive to mass produce design too. The laser heat issue is interesting. There are light sources with higher efficiencies, it is a matter of getting more efficient light sources and converting them to laser, or more efficient lasers. I know stuff about doing this except for the polarization need. Obviously there should be something something simply out there for that too.

Anyway, questions, how efficient are the most efficient lasers now, are we still talking about above 10%? The most efficient light sources I have heard about is at least 80%, anymore effecient ones than this? The Australian one that does at least 80% efficiency that is a trade secret, I suspect uses a technique I also came up with years before, in trying to theorise how to make a 100% efficient light source (theoretically, but then again, the solution to potentially eliminate the last fraction of percent loss in the real world just flashed through my mind).

Really !

Have you seen the amount of positional jitter in the thing ? Even if you lock the x scan with a clock derived from the mirror position, you still have the rubber banding of the Y axis to get locked. No easy method for that.
The mirror is tiny. it would fry under much more power. Remember it's 1mm with probably 5% absorbtion.
The 1mw lasers are obviously out. Are you aware it's hard to modulate lasers at 80Mhz?
So pretty much none of the thing is useful for up scaling to 4k high power.
Don't get me wrong, I personally love to get the cheapo techniques going, but I don't think there is much there in this case.
I'm happy to play devils advocate if you want to throw out some solutions ;)

OK Les, I read this on the plane (old magazine), turning a laser pointer off and on 500 million times a second cheaply, clearly in the range of shd, not that it applies.

It is not like the higher rates used in optical communications lines they have a technique for, or this:

http://www.newscientist.com/blogs/shortsharpscience/2012/03/record-breaking-laser-pulse-pa.html

(I had a cheaper design idea to do something like this, low yeild, also a pencil delivery, but accidentally left the paper work in a public space, only second time I ever did this, the other was just a inconsequential notepad with some ideas in the 80's. Probably not enough power for the size I was contemplating, but then again, another idea just occurred to me).

Because of my poor memory, and being seperated from research into the subject for years and being uncertain to the cost of certain parts, and taking your professional knowledge of the subject with weight, I gave the benefit of the doubt. But this 5% absorption, I realise you said probably now, which explains things (was it just 5% originally). I don't know the absorption % of silicon used, but I knew the rate should be able to be made fractions of a percent, by coating it with chemical vapour deposition, or other suitable technique, and I have a few ideas to enhance that too (but am unsure if the one I am thinking of is mine or previously done). Now, do you have any doubts?

http://en.wikipedia.org/wiki/Chemical_vapor_deposition

The solution I had in mind (well one of them) is so blindingly obvious, that you should have been able to guess it.
 
Still, I am worried about laser steering of the scanner mechanism at high powers (that I maybe be able to compensate for in a similar system) and possible fracturing/marring of the reflective surface.
 
Ok, > 99.999% reflective, but then you have the angle of incidence problem, and i think I can get around that a couple of ways.

http://en.wikipedia.org/wiki/Dielectric_mirror

I remembered Dichroic filters, that is why the 5% figure did not ring true in particular.

Here we have a broad spectrum:

http://en.wikipedia.org/wiki/Cold_mirror

This no true one way mirror thing interests me, I've worked on it multiple times, just thought up another solution as I was typing that, really interesting and a great method for technology use.

http://en.wikipedia.org/wiki/Mirror#Two-way_versus_one-way_mirrors_and_windows

I've come up with multiple possible solutions, one way more certain. The truth is, as long as you can reduce the light one way to great enough degree, you can have an effective enough solution for the public.

This device I just found looks like one of my ideas for an one way optical device:

http://en.wikipedia.org/wiki/Faraday_isolator#Polarization_dependent_isolator

Looks like some of the same method I came up with for an early flat thin lens design. Actually, I also was once came up with some similar direction of one of these techniques considering for a variable density filter stage, to bring a large dynamic range down into the range of a cheap sensor. My idea, and claim my original invention of the concept. No need to make your own, a cheap consumer sensor can be made to perform professionally. Of course, I abandoned this version due to obvious issues.

Also solves the other issue, now I think of it.
 
Hmm, I think I now better understand add and aspie in terms of low latent inhibition as well. Very interesting.

Marvelouse, my cognitive function has taken a huge dive since getting off the plane locally, due to some allergic immune response to something in the air around here, but my health is still sufficent to pull this stuff out.
 
OK, the Offer lapsed on the 28 th of September 2012, over and done with.

My own 3d techniques go from strength to strength. I now have several auto 3d techniques desperately in need of funding. In the meantime, I am moving onto other things optical, and locating alternative, temporary, projection devices for my products.

I leave all the competition with their quaint, maybe overkill in some cases, auto 3D products. Eventually history shall prove who is right, as it often does with what I come up with. The future is totally amazing, I often spend time there.
