1) What optical sensor are you using?
2) What angle of arc is subtended by the tape at the radius where the sensing is taking place? In other words, what is the width of the tape (in the circumferencial direction) where it passes under the sensor, and how from the center of rotation is the sensing element located?
3) What wheel speeds were you measuring?
4) Were you indeed "having the sensor count rotations" or were you using the FPGA to measure the period? (That's an important distinction).
5) What speed control algorithm did you use?

I can definitely get an answer by tomorrow. I wasn't the one who worked with the optical sensor.
