Abstract
A new active homodyne sawtooth fringe counting technique is described for eliminating the directional ambiguity in incremental readout of interferometric strain gauges. Results of quantitative strain measurements using unbalanced Michelson and capillary based instrinsic Fabry-Perot sensors agree reasonably well with the readout of a resistive strain gauge as well as with the theoretically predicted sensitivity.
