CHARACTER EVALUATION APPARATUS OF PAPER RECORDERS MATERIALS

摘要

PURPOSE: A device for evaluating properties of a paper documentary is provided to evaluating the properties of the paper property evaluation without damages. CONSTITUTION: A device for evaluating properties of a paper documentary comprises a near-infrared reflectance spectroscopy(100), a display device, and a protection module(200). The near-infrared reflectance spectroscopy includes an optical fiber probe irradiating lights to the paper documentary desired to evaluate and receiving the reflected lights and splits the received lights by a Fourier Transform. The display device receives signals from the near-infrared reflectance spectroscopy, thereby displaying the same as a spectrum. The protection module surrounds one side of the optical fiber probe, thereby protecting the same.
