METHOD FOR REMOTE MEASURING TEMPERATURE OF MOVING OBJECT

摘要

FIELD: physics.;SUBSTANCE: method involves optical reception of the thermal radiation signal of the object, spectral decomposition of the signal, formation of an radiation spectrum image on the surface of a matrix of receivers, signals from the outputs of which are approximated by approximants of a Planck function database for a set of temperature values. The most accurate approximant is selected and its corresponding temperature value and error are output. The same signals from the receiver matrix are approximated using the database for a set of images of the object. The most accurate approximant is selected and its corresponding error for identifying the image of the object is output in form of a drive alignment signal with possibility of aligning the optical system in the direction of the moving object.;EFFECT: higher accuracy of measuring temperature of a moving object owing to automatic alignment on zero bias of spectral decomposition and use of energy of all receivers in the receiver matrix.;1 dwg
