Abstract

An imaging apparatus comprising: an optical fibre with multiple monomode cores; at least one coherent radiation source for transmitting coherent radiation into the monomode cores and a modulator for modulating the coherent radiation input to pairs of monomode cores, each pair of monomode cores being associated with a unique modulation, wherein radiation output from each pair of monomode cores forms an interference pattern on a target to be imaged, and each interference pattern is uniquely identifiable from its unique modulation as originating from a specific pair of cores. A detector is provided for detecting radiation from the target. An analyser analyses the detected light and forms an image of the target.
