Abstract :
By means of the centimetric resolution of the developed cut-back method, we have directly observed a rotation of the birefringence axis and a sinusoidal evolution of the local retardation along spun fiber samples, confirming theoretical predictions regarding how the spinning process acts in reducing the internal fiber birefringence.
