photodiode detector circuit

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 with amplifier circuit and LED emitter circuit, with model spec.

Thanx.

hello
forthis i think first u have to design the photo diode amplifier and calibrate its output then refer it with the original signal. for light emitting please secribe more about your led specification

If you have no reference phase how do you propose to detect movements?

Also. I have designed a quite similar method.
