Made an infrared camera.
2005-05-09, 7:02 PM #1
It's a simple webcam hack. I bought a cheap webcam, opened it up, removed the infrared filter and replaced it with some photograph negatives. Now it only recieves infrared light (basically, it isn't perfect yet).

I'm gonna do it a little more cleanly later, these negatives have my prints all over them, but the quality is decent for a $20 webcam that's been tampered with.

Any projects you have going on?

To be honest, I saw info about the mod online and was just curious.

I mean, it's an entire spectrum of light God didn't intend me to see.

Yea, thats pretty snifty, especially for a 20 dollar camera.

I cleaned up the negatives, and used less of them, so the picture's about as clear as the unmodded camera. It didn't have this green tint at first, but after a while it started to show up.

Anyway, here's some phenomena that happens in infrared.

1) These are the safety features on the reverse of an american $10 bill. They only appear in infrared.

2) This shirt is actually dark navy blue, yet appears white. I'm not sure what it is, because some clothing stays dark. A friend was wearing a black shirt and navy shorts; the shorts stayed navy while the shirt appeared white.

Are you receiving reflected infrared from a light source (or heat source)? These images don't really look like passive infrared images in my opinion.

Infrared is not "heat vision" like you see in bad movies.

Infrared light is emitted by almost all light sources, including the sun. If you use a very good infrared camera with the right filter you can see through clothing under certain conditions.

I could use a pair of infrared binoculars...

I might give this mod a shot so I can catch those ******* kids that keep knocking over my mailbox. These kids aren't even creative anymore. At least when we were kids, we blew them up with homemade bombs and such.

Infrared is all wavelengths of light longer than 750 nm (the longest visible red light), but less than microwaves. Similarly, ultraviolet is the light of a higher frequency than visible purple, but less than x-rays.

Keep in mind that I'm filtering out visible light with camera negatives, which aren't the best filters.

do you have to replace the filters often, or can you just leave one in?

No.
nope.

It's not faked, it's just makeshift. It operates on the same principle as expensive infrared cameras. You remove the infrared filter and the camera now recieves infrared light. The camera negatives filter out visible light, but being camera negatives and not a true visible light filter, they don't filter out all of it and the quality suffers a little.

The filters should work indefinitely.

Cameras Jon`C mentioned use filters designed so that nearly all the light percieved is infrared. I could probably find a better material for it, but the negatives work, as you can see with the shirt and $10 bill. It isn't so refined that you can see through clothes, but it cost a total of $20 and that isn't why I built it.

My camera phone has been raped now. I'm trying to take the lens off again, but it doesn't look too good right now...

I thought, it would've been cool if I could have a portable real-time IR camera. But.. it didn't turn out too well. I'm going to smash it against a wall tomorrow, or brick it, I'll post picks.

Sony actually sold a phone, off the shelf, that was capable of this. After it became public knowledge they pulled it, and made the IR feature only function at nighttime.

Sure, Mr. Heat Vision, but actually it is. But I'm afraid I haven't seen those bad movies.

I suppose what I was thinking would require special software to recolour observed intensity levels. It would then be more clear then to use for example to scan computer interiors for heat distribution and success of your cooling solutions, or even to scan how good the insulation is in your freezer or house (room). However, it might require a more sensitive camera. And total darkness to eliminate the visible wavelenght noise the make do filters let through.

However, this is very cool nonetheless! And the temptation to try this is very high indeed...

Well, IR is electro-magnetic radiation that's close to wavelengths put out by heat, but it's not really "heat vision."

Like the time I was on a field trip to the fire station, and they let us try out the IR things. Apparently, "things" could be seen.

Firefighters often use IR gear because it sees through smoke more easily than the naked eye.

Super 8MM Cameras used to have a nightvision mode that would see through some women's dresses. Needless to say, the specific nightvision mode has been pulled at retooled.

there are different ranges of IR. near IR (NIR), shortwave IR (SIR), midwave IR(MIR), and longwave IR (LIR).
the kind of IR that allows you to see undergarments is NIR. the heat vision thing on military equipment is either MIR or LIR.
short, mid and longwave IR is heat.

btw, cool that you did that with your camera. :)
