A two-wavelength readout method is developed that maintains high sensitivity while increasing the detection range from 105nm to 1.7um assuming sensitivity is maintained at > 50% of the maximum sensitivity.optical sensinggrating interferometryMEMS metrologyTwo-wavelength grating interferometry for extended range MEMS metrologytext::conference output::conference poster not in proceedings
