Infrared "seeing" glasses

[glowdye]

That guy selling the IR glasses stole the idea from me. Thats why he is trying to cover his tracks by calling himself sole inventor. which he is not. I got the idea from the amasci site four years ago. I developed them and finally got a manufacturer to make the lenses the same color as the congo blue gel filters. i spent money on patent pending apps and a trademark.
i couldn't compete with a lier who is saying his glasses work by electron multiplication and is lying through his teeth about seeing heat and x-rays. Believe it or not but this guy lives in the same city as i do. he overheard me talk about these glasses to the postal clerks. I spoke to him on the phone and I won't say any kind of slander or libel but I will say that the glasses I sold were of much higher quality than his and I can prove it in a court of law and that I" invented" these way before he did.

hey Aseras, you mean green right?
blue diodes use quantum dots i think.

i made some proper IR glasses. using an old camera phone and a fat convex lens, i mounted the lens to the frame of some glasses and mounted the camera in front of the lens so it is in focus and i had myself some ultra cheap IR goggles. oh yeah the camera in the phone was modified to remove the IR filter so it could see IR more clearly (CCD chips are ultra sensitive to IR, without the filter all colour is drowned out by IR from any incandescent light source)
I should mount some IR lasers on it and make night vision goggles.

Did you use the cell phone's display infront of the lens? I would be very interested in seeing a picture of it..

Are there "plans" available for something like this?

Agreed, Pseudo - everyone on here that has seen my "dangeropus demo" video has seen 808nm IR as well.

Since i was just playing with an IR LD a few days ago, i think i know exactly which red "glow" you mean..

I put the LD into an aixiz module, tried collimating the beam, while observing it through a CCD, and noticed this faint red light..
I managed to collimate this red light into a dot, and in the end the IR beam was quite straight..


But i thought this red light is just a byproduct. Especially since on the camera the IR light floods a much larger area around this dot..


The red light looked just like plain old red. But now that i read the diode lasers produce one wavelength only, i don't know what to think..

its really not worth taking a picture of
i will see if i still have the frame, i will have to re attach the camera phone. yeah it used the phone screen. it was pretty shite video quality
this is the guide which inspired me to do it (i picked up the phone at a garage sale for a couple of bucks) http://www.jawish.org/blog/archives/17-Hacking-a-SE-T610-camera-for-IR.html
the same thing could be done with any camera, they all have IR filters in them somewhere, usually looks like a pink piece of glass
by the way if you destroy the IR filter it renders your camera IR which gives very strange pictures that you will probably get sick of

if you look at a IR laser through a ccd, you will probably only see what you can see with your naked eye, that is if it has an effective IR filter.
it is easy to see a cd laser when it on. or at least for my young eyes i do try not to make a habit of staring into them though

Don't CCD's have the inability to see above 1200nm becuase the light pass through silicon at those wvelengths?

 

[woop]

probably but why does that matter? most led's and lasers are not that deep IR

That's interesting.. I have that exact phone (T610) and could use it..

But for better picture quality i could use a Siemens M65...


Just one thing.. What kind of a lense do i need to be able to put this in front of my eye and see the display clearly? Would a disposable camera lense do?


It would be great to be able to safely use an IR laser, and collimate it's beam and so on..

With some powerfull IR LEDs it could be used to make night vision goggles.. Maybe if i mounted everything into some protection goggles..


But i'm wondering.. How much of the originall phone's circuitry do i have to keep? I would guess everything, since how would i activate the camera and display otherwise?

That's true.. The specs sheet i've seen state the IR LD (for CD burning) at 725nm if i'm not mistaken.. Maybe slightly higher, but definatelly under 800nm


The laser i made out of a very fast CD-RW drive had a beam that was quite visible on a webcam, if i puffed some smoke through it..

If i removed the IR filter it would be even better..


But i had an idea..

What would happen, if i took this IR filter out of a CCD camera, and put it in front of a "cheap" 200mW DealExtreme green laser?

Would i get an IR "free" beam? Just a thought...

i used a convex lens. the fatter the lense the closer you can mount the camera to your eye and the bigger the image would be. i used some lenses out of an old polaroid camera, from the viewfinder, it had lots of lenses in it.
somehow i managed to get the image in the camera eye to be exactly the same size as the image in my normal eye.

when you remove the filter, it becomes very easy to saturate the camera with IR because its so sensitive. so a IR laser dot would look to the camera like maybe a few watts of green would look to us. VERY bright.
and remember that by removing the ir filter you ruin your camera as a normal camera. no more colour

That must have been it.. Thanks!
