ABSTRACT:
A method and apparatus for measuring relative deflection of interspaced toothed wheels or their equivalents on a less than once per revolution basis. Deflection measurement errors due to wheel imperfections are measured and stored for each tooth pair and later used to correct deflection measurement on a tooth pair basis. The apparatus includes a sensing circuit which is operative to provide a signal when teeth pass a fixed position, a duty cycle to digital hardware circuit which is operative to measure the duration of the state of the sensing circuit signal, and a computer which is operative to compute, store, and apply correction factors in response to the duration of the state of the signal.
