ABSTRACT:
A thermometer includes an infrared sensor (14) for receiving infrared radiation to generate a corresponding electrical signal; a reference unit (10) for emitting a standard infrared radiation; a temperature sensor (11) for receiving the standard infrared radiation to generate a corresponding standard electrical signal; a support unit (1, 2) for supporting the infrared sensor and the reference means such that the infrared sensor receives the standard infrared radiation from the reference means in a standby state and infrared radiation from a subject in a measurement state; an arithmetic unit (44) for computing a temperature of the subject based on the electrical signals from the infrared sensor in both the standby and measurement states and from the temperature sensor.
