Abstract :
A new, simple and very promising technique for spot-size measurements in single-mode fibres is proposed, based on a spatial filter which modulates the optical beam at the output of the fibre. Its inherent simplicity, accuracy and high efficiency make it attractive for laboratory and factory measurements.
