FIELD: instrumentation.
SUBSTANCE: detector comprises matrix of suspended bolometers located at lens focal plane, sensing circuit generating the flow of unprocessed values and gate. Process of correction comprises the steps that follow. Compilation of general table of unprocessed values. Determination of the table of shifts correction for detector current temperature in compliance with said general table and the set of stored tables of unprocessed values. Flow of unprocessed data is corrected with the help of the shifts correction table. In compliance with this invention, servicing procedure comprises check of conditions for replacement of the table from said general set by general table. In case this condition is satisfied, table of said set is replaced by general table. Check is performed to verify if a new set of tables exists after said replacement, more suitable than general set for further determination of shifts table.
EFFECT: correction of the shift of detector with thermo electronic cooler of pre-calibration.
