ABSTRACT:
A method of measuring temperature by the use of an infrared sensor is capable of measuring temperature with high accuracy without being influenced by thermal drifts due to conditions of the atmosphere and environment before the start of measurement. An infrared sensor is associated with a normally closed shutter. The shutter includes a plurality of openings, such that one starting signal provided to the shutter produces a plurality of output signals from the infrared sensor 6 by a single reciprocating motion of the shutter. The first signal is excluded or averaged with the subsequent signals in calculating temperature.
