hi'
I'm going to design a simple fibre optic vibration sensor. This is how the system works:

LED illuminates the optical fibre and the light ray propagates inside the fibre and the change of transmission properties of the light propagating in the fibre will be detected by a photodiode detector.

I need the design of the photodiode detector and LED emmitter circuit, with model spec.

Thanx.
 

Re: fibre optic sensor

Everything depends on what are you going to transmit over fibre optic link ..
For example, for simple audio transmission, have a look at:

If you need fast data transmission, you may consider HFBR modules from Agilent Technologies ( data sheet can be downloaded from: **broken link removed** )
