I want to know how this system determines the location of the imbalance, knowing that by using signal processing techniques we do not obtain this location, and to find the correction location we use the influence coefficient technique.
It's measuring the peak of the sine wave produced by the accelerometer, and the timing from the sine wave peak to the pulse from optical sensor and displaying the timing difference in degrees from the reflective tape location. I've made a home made version using an Adafruit accelerometer and an optical sensor I bought from Amazon, feeding a 2 channel oscilloscope; channel one is the sine wave and two is the sensor pulse. Measure the phase difference on the oscilloscope display and calculate the degrees.
