Homework Statement
Well, I´m doing a project about FSO (Free Space Optics), it deal with optical communication but without fiber, only by air. Then, I have already studied the transmitter (gaussian source), the channel and I know I need a photodetector APD for the receiver but my questions is: how can I study how much power there is on the receiver?
I also know power on the receiver is the difference between power on the transmitter and loss on the way. Nevertheless in the receiver a bit of power is lost because of the aceptation cone.
So how can I calculate this energy loss??
Thank you for help me.
