MULTICHANNEL DEVICE FOR MEASUREMENT OF PYROMETRIC CHARACTERISTICS Russian patent published in 2009 - IPC G01J5/60 

FIELD: physics, measurements.

SUBSTANCE: invention is related to metering equipment. Device represents a polychromator with fiber optic input, concave diffraction grid and multi-element row of photodetectors at the inlet. Photodetectors are connected via signal amplifiers to programmable commutator. From the commutator outlet signals are supplied via ADC to personal computer. Fiber light conductor serves for transmission of signal to a safe distance, and also for averaging of spatial heterogeneity of investigated object. Deliberately large amount of spectral channels makes it possible to select wavelengths by programmable method, which will be optimal for investigation of this object, and also by grouping of row elements to form band filters of rectangular shape with specified width in set wave lengths.

EFFECT: improved accuracy, information value, expansion of dynamic range of measurements.
