Phase Imbalance Optimization in Interference Linear Displacement Sensor with Surface Gratings

Phase Imbalance Optimization in Interference Linear Displacement Sensor with Surface Gratings

In interferential linear displacement sensors, accurate information about the position of the reading head is calculated out of a pair of quadrature (sine and cosine) signals. In double grating interference schemes, diffraction gratings combine the function of beam splitters and phase retardation de...
