Two ultrasonic articles

Is the same as IR. The ray is used as a bridge, as an antenna, the phenomenon "travel" on it and arrive. There are small chages in frequence. The transmitter is the receiver also because catch the small alteration.

How can be that way ?

The IR led just emits IR light!

Then what ? The signal travels on IR light beam ???

That way it's impossible.

Or do you mean something different ?

Kind regards,

Somewhere I have an email from the final owner of Poptronix giving me permission to post complete articles from any of the old issues, which includes Popular Electronics. So post whatever you want.

Don't wish repeat a think repeated 100 times!

I think to remember you said the beam kind of ionized the air who allowed the HV to travel trhu it,right?
After all it´s all about the same idea, the burried "oxided" metal creates a deformation in the electric gradient, as does your IR .
I wonder how you PD reacts to a rod partially burried and sticking out about 50cm out of the ground ?

Hi Fred,
yes... but to ionize free air you need more than an IR led!

I remember too that things Esteban wrote... but then no clue of how the hell the air is so different from here there in Paraguay!

Also... Paraguay climate is hot and humid... then static electricity is very hard to detect in such environment cause of leaks due to the water vapours there....

Uhm... I think the IR led can't do anything apart some science fiction... don't see a way how that stuff could give extended range of detection... for me it's pure speculation.

Kind regards,
Max

You read Carl's post... now can post articles if you want...

But I know... are just about BAT detectors and the like...

Just to have "ideas"...

So... ideas to make a gold-sonar I think!

Kind regards,

I think the "idea" beyond this concept is that the IR beam is supposed to act like some sort of probe that establishes a "connection" (or signal line) to the target. Perhaps the PHENOMENON is somehow transported along the beam ... pseudo-scientifically speaking, of course.

A beam of IR light –in this case modulated– is an antenna with the advantage free of interference as a metalic antenna. Here exist a tone in receiver. So, you can made with it the job.

The same with ultrasonic.

This explanation sounds similar to my previous suggestion. I called the beam a "probe", but you've called it an "antenna".

Hi,
but... from when an IR light beam is an ANTENNA ???

An ANTENNA MADE OF PURE LIGHT, MAN !

I hope you mean here and not in some parallel universe!

Seems much of these concepts about LRL were developed as japanese cartoons of the 70's....

I think I found the plan of such an LRL...

You don't learn nothing about admin rules about posting such figures.

The same occurs when you post clowns figures. And don't know why admins don't remove these figures. And ROberts' figures.

[Esteban]

Max, you need to made a few effort and type on the web the words infrared antenna. The light consist in photons and a train of photons is a beam. Each photon is a nanoantenna and a beam is a large antenna. This is the reason you can transmit voices in others via this beam. If you can transmit, you can receive.

Uhm... you're losing sense of humor I think...

Don't you like japanese cartoons ?

I don't know why the most "sense of humor" is used on RS forum...

I think that such images don't contribute in it. And consume bytes.
