POLYCHROMIC PYROMETRE Russian patent published in 2009 - IPC G01J5/10 

FIELD: measuring technology.

SUBSTANCE: polychromic pyrometre is equipped with a rotating mirror scanning an object image. Photo-receivers are arranged along circumference, radius of which is equal to distance from the axis of mirror rotation to a focus of an optical system of the pyrometre. Each photo-receiver has a corresponding spectral filter letting through radiation of specific wave length. With rotation of the mirror the image of the registered object alternately comes into the photo-receivers in corresponding sections of spectre. The photo-receivers are connected with a micro-processor controlling a temperature indicator.

EFFECT: upgraded accuracy of measurements.
