| 520 | $aFibre counting is a onerous and time consuming task. The blank field method has been proposed as a means of easing that task. In this, successive microscope graticule areas are scanned and note is made of those void of fibres. At some defined stopping point the fibre density is estimated from a function of the total number of voids and total areas scanned. This approach was used in two planned experiments to investigate the bias, the variability, and the time savings of the method compared with the standard technique of fibre counting | ||
