Fast I/O – Fast input

Hi all,

I need to read a fairly fast input signal.
It is in fact a large light bridge that blinks when a circular disc spins through it.
I would like to sample the input signal every 10 ms, and it has to be stable. What I/O device would be best to use?

Maybe some simple serial device, maybe a keyboard encoder?
N.B. we tried a Phidget InterfaceKit, for example, but it will not give a stable reading every time.

Any suggestions appreciated.
greets, Woody
