| Abstract: | A method for accurate reflectance measurement is described. The technique introduces a variable attenuator in a recirculating loop to calibrate the reflection provided by a fictitious reflector. A formula for this calibrated reflection is given. The device allows accurate measurements of the backscatter parameter of a fibre.<> |
