Anyone use a laser thermometer?

Long time I insist in it... Just with the beam of 2 IR leds (for me, better), long time ago (since the end of the 70s) we have experimented... You can added lenses for more distance, but today there are IR leds with incorporated lenses wich can cover 100 meters.

100 pounds of gold just under surface can be detected by IR scaning for sure. Such finding can be detected from airplane too, but no single gold coin at dept of 5cm can be detected by IR scaning method. Never.

Parascientific dreams, nothing more.

Hi Esteban,
The tests you made are not the same as using an IR thermometer. Your circuits monitor the audio frequency pulses of a square wave pulsed LED emitting a beam. No IR thermometer or thermal imaging camera emits an IR source signal directed at a target. They are passive temperature measuring instruments. These are not even similar to your IR experiments that are designed to direct an IR beam at a target. The principle of operation is different, and the results are definitely different, as is expected from completely different instruments.

Yes, you're right. I think you can convert an IR laser termometer for to find buried metals. But also consider the beam as an IR "camera".

An IR camera??? What do you think is happening that makes it a camera?

Carl used words IR camera. I take it...

We are talking about two different IR temperature sensing devices. When Carl talked about thermal imaging cameras or IR cameras, he was not talking about the IR thermometer. The camera consists of many IR thermometers arranged in a grid with a lens to focus a thermal image on it. This is the same idea as using a light camera to focus a light image on an image sensor.

The thermal imaging camera does not send out an IR beam at the target, same as an IR thermometer does not send out an IR beam at a target. They onlly measure the temperatures where they are pointed.

But if you can modify either of these to find treasure, then post the details of your mods here so we can all try it out to see how well it works.
