摘要：

Fused bundles of 60 mum diameter scintillating fibres with square cross sections of 2.5 mm edge length, were illuminated through 2 m length and their exit faces magnified and then photographed with a highly resolving CCD-camera. Subsequently, rows of individual fibres were selected with an appropriate slit or grid in front of the entrance face. The pictures taken, stored in MacIntosh computer, were processed to determine the coherency, the intrinsic optical precision and the resolution of these bundles without distortions by optoelectronic readout systems: the precision (sigma) varied from 18.4 to 22 mum and the resolution from 42 to 55 mum, depending on the angular deviation from parallel slit orientation.
