| 577609 | 2007-08-07 06:19:00 | Hi all, In my experience this forum is quite technically minded and I have an idea I wonder if anyone can answer or consider: I have lost a ring (white gold) in some thick grass/ scrub and although I know the general area where it must be, the chances of finding it are pretty slight since it is rather over grown. I am wondering whether a type of flash photography exists whereby a certain 'flash' of radiowave can be emited that will pass through grass and brush (doesnt need to be strong enough to pass through the ground) and reflect off said missing ring back to a specially tuned sensor in a camera which can thereby help locate the missing metal object? To help locate it I figure a grid could be placed on the ground with other metal objects that will ease finding the ring. Hmm, just an idea - how plausible is this, or does such a method already exist such as this? Thanks for yall's ideas, John. |

| 577610 | 2007-08-07 06:25:00 | No. ;) But metal detectors do exist. One of those would certainly find every drink can tear ring in the area; it might even find the ring. You might be able to hire one, or find someone who will show one off. Try a bottle collecting club ... I'm sure their interests extend beyond glass. |

| 577611 | 2007-08-07 06:26:00 | Superman could do this with NO flash at all...but Unless you have something a little more ...er...powerful than a flash on your camera for locating a metallic object....well...I don't think so. A metal detector is the better idea I feel. I wonder if you can rent one or find some guy on the beach treasure hunting with one to drop by for a spot-o-tea and "incidentally, Gov, can you do me a small favor, since you've come all the way over here"....and all that. |

I used the illustration of a standard camera 'flash' just to give a notion of what I am thinking of. I thought that such a method might be possible in a similar way to x-ray photography. Does xraying always require a reflective screen behind the subject though? I guess for my hypothetical system to work, one would need to focus the radiowaves onto the camera sensor which may not be easily doable. Any other reasons why my idea couldn't / wont work? I'm genuinly curious. Cheers for the replys. -John. |

| 577614 | 2007-08-07 11:11:00 | Elimination is the quickest way out. Take away everything that is not a ring, and pick from what is left. And for your idea, ever wondered why you cant see tv programs on a camera? Same problem, different stuff involved. Cameras detect and record light, from infra red up to the top of the visible spectrum and occasionally into UV. Radio waves are a long way lower in frequency than light. Compared to optical frequencies, micro-waves are maxi-waves. How's that for disjointed? |

| 577615 | 2007-08-07 11:34:00 | It may be a good idea if you actually learned about how x-rays work. A little too much to tell here, but use thiswikipedia (en.wikipedia.org) search which explains it well and google. A few sites about similar people loosing their rings: http://www.mineoro.com/ Here (ezinearticles.com) Hope you manage to find it. |

| 577617 | 2007-08-07 14:26:00 | yes you could; entirely plausible but i dunno if i'd call it feasible why not just burn the grass? should only need a leafblower and some sunlight after that... or does the missus not know yet?:D |

Thankyou for your advice, but I do know that your everyday camera can only see visible light (and sometimes infra red light with some modification). What I was asking were possible or not, was a theoretical system based on the analogy of a 'camera' and 'flash' that was operating on a different wavelength. |
