Abstract: An improved tympanic thermometer incorporates twin thermopiles, each including a set of sensing junctions and a set of reference junctions configured so that three of the four sets of junctions sense only the temperature of an ambient environment, while the fourth set of junctions receives energy from both the ambient environment and from the tympanic membrane of a patient whose temperature is being taken. The energy received from the tympanic membrane is intentionally not bandwidth limited, enabling an accurate temperature measurement to be calculated which is substantially independent of wavelength. A light pipe is optionally included to assist in carrying radiation from the tympanic membrane to the fourth set of thermocouple junctions used for temperature sensing. In the preferred embodiment a dielectric coating is internally applied within the light pipe, and interchangeable tubes may be provided which conform to the aural physiology of different patients, including children.

Abstract: An infrared detector receives infrared energy from the target and provides a detector signal based primarily on the difference between the infrared detector temperature and the temperature of the reference temperature area of the detector. A contact temperature measurement device provides a reference signal which is a function of the temperature of the reference temperature area of the detector. A processor receives the detector and reference signals and combines the two signals in a non-linear manner to result in a signal which is representative of the temperature of the target. The method of non-linearly combining includes the use of gain and offset terms which may be altered to a limited extent by a technician in the field with a blackbody calibration source. As a result of the recalibration, accurate target temperature measurements are continually provided. Additionally, the method of non-linearly combining includes the use of additional gain and offset terms which are adjusted to account for the infrared radiation characteristics of an anatomical target as compared to blackbody calibration source targets. Temperature is determined by combining a polynomial function of the detector with a polynomial function of the reference signal.

Abstract: A temperature measuring apparatus is provided for determining the temperature of a target material to be measured as compared with the temperature of a spaced reference source which has a temperature control for controlling the temperature of the reference source. A differential radiation detector having a first detector exposed to the target material and a second detector which is shielded from the target material and exposed to the reference source provides a differential output or error signal which is used to control the temperature of the reference source. When the reference source temperature is the same as the target, the temperature of the reference source is read out which is the temperature of the target material regardless of the emissivity. The differential radiation detector is positioned in spaced relation to the target material and is focused onto the target and the reference material and the error signal generated is used for controlling the temperature of the reference source. The reference source is preferably a heated plate having a step in the center thereof with a hole therein through which the differential detector means views the target as well as the plate. Using a hole prevents reflection from the target back through the plate to areas of uncontrolled temperature.

Abstract: A system for measuring temperature within a region to be tested includes a sensor means responsive to the temperature within the region for transmitting light energy along an optically-transmissive path and detector and amplifier means responsive to the light energy for producing an output signal which represents the intensity of the light energy. A signal processor electronically calculates a display signal from the output signal which represents the temperature within the test region. The signal processor performs this calcuation by solving Planck's equation, and a successive bisection technique is utilized to achieve extremely fine resolution of the temperature.

Abstract: The present invention provides new methods and their associated materials and devices for the remote optical measurements of temperatures with luminescent sensors. These methods allow the use of a single sensor to measure temperatures over a wide range from the cryogenic regions to well above ambient temperatures, up to about 800 K depending on the sensor. Using fiber optic links a single, inexpensive light source, for example a light emitting diode, and a single photodetector are used to obtain normalized measurements from a sensor, only minimally affected by fluctuations in the intensity of the excitation light source, fiber and/or connector losses or detector drift. One preferred embodiment of this invention can be used with most luminescent materials and does not require a temperature-dependent change in the luminescence properties of the sensor within the temperature range being measured. Another preferreed embodiment uses temperature-dependent luminescence decay times as temperature indicators, using a class of materials the luminescence quantum efficiency of which does not degrade within the temperature range being measured. The invention permits the use of a single sensor in two independent operative modes, thus providing redundancy and a self-checking feature.
