Hi everyone,
For a project i'm doing i'm going to try and set up a free space data transmission using a modulated laser. I'm pretty confident on the theory in terms of how this can work i'm just not too sure on how to interface such a system with a computer. I'm planning to take a computer file and convert it to a binary string (1s and 0s) and then use this to switch the laser on and off. Then as a reciever have a photo-diode to measure the laser pulses and generate an identical binary string. This can then be converted back to the specific file type.
I'm really not very experienced in programming or computer interfacing of this sort so if anyone has any suggestions then they'd be really really appreciated.
Thanks in advance
Paul
