Tatam, Ralph P.Ezbiri, A2017-01-112017-01-111996-03http://dspace.lib.cranfield.ac.uk/handle/1826/11243This thesis describes new signal processing techniques applicable to miniature low finesse Fabry-Perot interferometric sensors. The principle of operation behind the techniques presented resides in the use of the axial modes from a single multimode laser diode to produce a series of phrase shifted interferometric outputs in conjunction with the path imbalance of the sensor microactivity.en© Cranfield University, 1996.
