This set of two circuits from the basis for a very simple light wave transmitter. A LASER beam is modulated and then aimed at a receiver that demodulates the signal and then presents the information (voice, data, etc..). The whole thing is very easy to build and requires no specialized parts execpt for the LASER itself. LASERs are available from MWK Industries. |

| Can someone please tell me how do a laser torch - based voice transmitter and receiver works ? | ||
| What is it with all these students that don't know shit about electronics. If you can't figure out how to transmit data with this schematic so nicely laid out for you then maybe you shouldn't be playing with lasers. | ||
| thank you for simple diagram...i want to use this to trnsmit data to my com.........how it work? and what are 2 modem chips thnks again | ||
| Replace the laser they show with a laser pointer.
Oh, and if you simply hook it up to a headphone jack you eliminate the need for a speaker as well,as a pair of headphones will act the same.
As shown, this mother is costing about $400-$500
scitoys.com has a better explaination (Editor's notes: $400-$500?) |

| how close are to today's light transmitters and receivers to those conceived by Feynman almost 50 years ago??? | ||
| i am very happy in this moment.because i want to make a laser project.this circuit is suitable for these project.thank you | ||
| this might be the thing that i need. Unless it is an amplitude modulation circuit. pls send and email to me if you have any idea on how to construct a laser FM audio circuit. thanks. btw, i am a Computer systems Engineering student in De La Salle University Manila. | ||
| respeted sir, you didn't give any detailed about laser beam on your text and how it will work? | ||
| please, would u suggest what are the applications and advantages of this? | ||
| hai sir i am pkumar, please would you give brief description about this circuit.Has like to do seminar on this project. | ||
