This paper presents an all-digital close-loop operation based on DSP circuits, which uses the two-frequency serrodyne modulation to modulate and demodulate the optic route.
We have 15 millionths of a second to measure the noise, run it through a little DSP processor, compute that inverse signal, and pop it out through the driver.
