The main principles of the operation of fibre-optic tomographic sensor
s are formulated. The ways in which they differ from the known tomogra
phic analogues are considered. Potential capabilities, future developm
ent trends, and applications of these sensors are discussed. A brief r
eview is given of the literature on fibre-optic tomographic sensors. T
he main parameters of the constructed sensors and some results of expe
rimental investigations of scalar and vector physical fields are given
.
