Infrared thermometer
Accurate temperature measurement has long been an objective of researchers in a variety of fields. Temperature sensing of patients is of particularly acute concern in the health care field due to the high correlation between patient health and body temperature. The temperature of an object, such as human body, can be determined by two methods: either by a contact thermometer having a probe which comes into physical contact with the measured object, or by a non-contact thermometer which measures infrared (IR) radiation exchange between its radiation detector and an object (target). Infrared thermometers are well known instruments for remotely determining temperature when it is neither possible nor practical to use a direct temperature sensing probe. The infrared light emitted by a target is transmitted to a photosensor which converts the light to electrical signals that are then processed or analyzed for conversion into a visual indication of temperature. The IR thermometer detects intensity of IR radiation which is naturally emanated from the object's surface. All surfaces at a temperature above absolute zero emit heat in the form of radiated energy. This radiated energy is created by molecular motion which produces electromagnetic waves. Thus, some of the energy in the material is radiated in straight lines away from the surface of the material. Many infrared thermometers use optical reflection and/or refraction principles to capture the radiated energy from a given surface. The infrared radiation is focused upon a detector, the temperature is then calculated and presented on a display. The IR thermometer typically includes a housing which may have a variety of shapes depending on its application. It is desirable that the housing have a probe containing a thermal IR sensor which receives and detects IR radiation from the object. An infrared clinical thermometer is equipped with a probe insertable into the ear orifice, and the probe is provided within the clinical thermometer body so as to protrude to the outside. Provided within the probe is a waveguide for guiding infrared radiation, which is emitted from the tympanic membrane to an infrared sensor disposed inside the housing.
