In case you haven't noticed, I am the OP. And I don't appreciate having my thread taken by someone else and then being notified when someone makes a rude and infantile comment about me.

I'm not trying to split hairs, I was wondering if his goal is to "see" the IR being emitted, or whether it is indeed to monitor the voltage across a matching photodiode and thus get an idea as to the frequency of the signal, etc.

I only originally joined these forums to resolve my own queries, and I believe I've obtained sufficient information on them now. I've suffered enough disrespect for trying to help others on here, I don't think I'll bother any longer.

All an oscilloscope shows is light emitted from phosphur activated by a beam of electrons - it can only ever show a representation of anything - but a representation is all you need. As he specifically said 'on an oscilloscope' he obviously didn't mean he wnated to see the IR been emitted.

hi giftiger.
No one is disrespecting you.
What you should appreciate most of us try to answer the question based on our experience in knowning that the posters first language is not English and trying to figure out what he is really asking.

There are a small number of people on this Forum who's opinions/comments I value and trust, at this time you are not one of them.
Dont take that as an insult, its not intended in that way.

It would be a sad loss if you quit because someone has criticised you.

You should have told the other 'OP' not to hijack your thread.

Regards

One can see an IR LED using a digital camera if the duty cycle is aproaching DC. One cannot see the waveform of a switched IR LED using a digital camera. One has to set up a device that will detect the photons emmitted from the IR LED (a phototransistor), and convert this to a corresponding voltage that CAN be detectected by a device that reads time variing signals, such as a CRO. Show me a device that reads time varying IR light, and displays it on a screen?

hiiii..just use an emitter follower at the output... it will increase the current.

 

Saw the diagrams,Will discus it after analysis.Reply you soon.Thanks
