Radiation type thermometer
First Claim
1. A thermometer comprising:
- an infrared sensor for receiving infrared radiation to generate a corresponding electrical signal;
reference means for emitting a standard infrared radiation;
a temperature sensor attached to said reference means to generate a standard electrical signal indicative of a temperature of said reference means;
support means for supporting said infrared sensor and said reference means such that said infrared sensor receives said standard infrared radiation from said reference means in a standby state and infrared radiation from a subject in a measurement state; and
arithmetic means for computing a temperature of said subject based on said electrical signals from said infrared sensor in both said standby and measurement states and from said temperature sensor.

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.
