Method and apparatus for non-contact temperature measurement

摘要

A method of monitoring the temperature of a target (4), the method comprising: a) sensing radiation emitted by the target (4) at at least two different wavelengths; b) determining a temperature value from the sensed radiation in accordance with a first predetermined algorithm; c) repeating steps a) and b) a number of times to generate a set of temperature values; d) selecting a target temperature from the set of temperature values in accordance with a second predetermined algorithm; and, e) generating an output signal defining the target temperature obtained in step d).
