Abstract
Apparatus comprising a source (1) of electromagnetic radiation; a sensing network (5) which comprises a plurality of sensing interferometers (10) each of which includes a wavelength filter for selecting a band of wavelengths (11) of electromagnetic radiation provided by the source (1) and is suitable for converting the magnitude of one or more physical parameters to a change in a sensor optical path length delay; a reference interferometer (7) for selecting a reference optical path delay; a wavelength selection device (8) for selecting one or more of the band of wavelengths (11) filtered by one or more of the sensing interferometers (10); and a detector (9) for converting the electromagnetic radiation selected by the wavelength selection device (8) to an electrical signal.
