ABSTRACT:
Method and apparatus for generating signals corresponding to the moisture content of paper by irradiating a sheet of paper with a near infrared ray, by detecting a beam having a coaction with the paper and by accomplishing the desired arithmetic operations with the use of the detected signals. According to the method and apparatus, at least two optical systems having different degrees of coactions with the paper are provided to respectively detect photometric optical signals and reference optical signals so that the signals corresponding to the moisture content may be generated with the use of the photometric and reference optical signals.
