FIELD: measuring technique.
SUBSTANCE: IR detector can be used for measuring humidity and mass of paper fiber. IR detector has IR radiation source, collimator, modulator-monochromator and light guide. Integrating sphere provided with IR radiation photoreceiver is disposed at output of light guide. IR radiation photoreceiver is connected with microprocessor processing unit. Light guide is made in form of truncate done with mirror side surface. Photoreceiver provides high level of signal-to-noise ration.
EFFECT: improved precision of measurements.
