METHOD FOR REMOTE MEASUREMENT OF TEMPERATURE FIELD

摘要

FIELD: physics. ^ SUBSTANCE: method for remote measurement of temperature field of objects is based on using a measuring thermal imager and involves selecting one or more reference areas on the surface of the analysed object, measuring temperature of these areas using a contact method, sending the results to the measuring thermal imager in order to determine the "pixel amplitude to temperature value" ration for specific conditions of the measurement session. Correcting the initial calibrating characteristic of the measuring thermal imager based on said ratios. Converting pixel amplitude values of the digital image based on the corrected calibrating characteristics into temperature values which are used during remote measurement of temperature in real time at control points from the reference areas. Temperature fields are determined by converting all recorded pixels of the digital image into temperature values, followed by smoothing the obtained values based on temperature of corresponding reference areas. ^ EFFECT: high accuracy of remote measurement of temperature field of aerospace objects under launching site or test site conditions with low extra hardware expenses.
