DEVICE FOR CONTROLLING PAPER PARAMETERS BY STRUCTURE THEREOF USING GRANULOMETRY METHODS USING LASER SPECKLE PHOTOGRAPHY METHODS WHILE FIXING STRUCTURE IMAGE

摘要

FIELD: paper.;SUBSTANCE: invention can be used for controlling paper parameters. Essence of the invention consists in the fact that the paper parameters control device by its structure using the granulometry methods using the laser speckle-photography methods when fixing the structure image contains the optical radiation source, a device for recording a structure image, a computing unit, software, wherein the optical radiation source used is laser radiation at wave length 532 nm, can install other sources of optical radiation, if required method of investigation, device has significantly reduced dimensions - 350 × 250 × 150 mm and weight - not more than 5 kg.;EFFECT: technical result is enabling reduction of device dimensions, as well as ensuring its versatility.;1 cl, 4 dwg
