Abstract

This paper describes a novel sensor designed to provide information on some basic variables of paper during its manufacture. Depending on the type of grade, the instrument is easily configurable to measure anyone of three variables, namely: dimensional variations of paper (shrinkage), flocculation and creeping (tissue paper). The paper presents the basic concepts behind each technique used and describes the human interfaces of this equipment. Finally, the problem of spectral rotation due to camera misadjustments is addressed
