Abstract
We describe here the application of capacitance micrometry to the control of piezo scanned Fabry-Perot etalons using a closed loop feedback system. This system removes the problem of the non-linear response and hysteresis associated with piezo-electric transducers and allows precise control of both etalon gap and parallelism.
