摘要：A signal conditioner to measure the length of an interferometric gap in a Fabry-Perot sensor (interferometer). The invention includes a light source, a Fabry-Perotinterferometer capable of spanning a range of gaps in response to physical changes inthe environment, a second interferometer that is placed in series with the Fabry-Perotinterferometer which does not filter any particular wavelengths of light but acts as anoptical cross-correlator, a detector for converting the correlated light signal intoelectronic signals, and an electronic processor which controls system elements andgenerates a signal indicative of the length of the gap spanned by the Fabry-Perot sensor.
