ABSTRACT:
In an illustrated embodiment, brightness, color, opacity and fluorescent contribution to brightness are measured by an on-line sensing head providing for simultaneous measurement of transmitted and reflected light. By measuring two independent optical parameters, paper optical properties of a partially translucent web are accurately characterized substantially independently of paper grade and weight. The instrument is designed so as to be capable of transverse scanning of a moving paper web on the paper machine, and so as to monitor desired paper optical characteristics with sufficient accuracy to enable on-line control of the optical characteristics of the paper being manufactured. Advantageously, several sets of reflectance and transmittance values based on respective common spectral response functions are sensed continuously and/or simultaneously during movement of the web.
