摘要： An apparatus for measuring a concentration of a substance in an eye (13) having a retina (17) includes a measurement light source (4) producing a measurement light beam having a first wavelength at which the substance has a non-zero first absorption coefficient. The apparatus further includes a reference light source (6) producing a reference light beam having a second wavelength at which the substance has a second absorption coefficient which is substantially equal to zero. The apparatus further includes an optical combiner (1) which is positionable so that at least a portion of the measurement light beam retro-reflects from the retina (17) and so that at least a portion of the reference light beam retro-reflects from the retina (17). The apparatus further includes a detector (9) positionable to receive the retro-reflected measurement light beam and the retro-reflected reference light beam. The detector (9) is responsive to light having the first wavelength by generating a measurement signal and responsive to light having the second wavelength by generating a reference signal. The apparatus further includes an electrical circuit coupled to the detector (9). The electrical circuit is responsive to the measurement signal and the reference signal to measure the concentration of the substance in the eye (13).

摘要： An infrared ear thermometer includes a detector head housing (12), a heat sink (30), a recess formed in the heat sink (30), a thermopile sensor (40) mounted within the recess, a thermistor (44), and temperature determination circuitry (14). The recess defines an aperture that limits the field of view of the thermopile sensor (40). The thermal capacities, the conductivities of the heat sink (30), and the thermopile sensor (40) are selected so that the output signal of the thermopile sensor (40) stabilizes during a temperature measurement. A method of determining temperature using the ear thermometer takes successive measurements, stores the measurements in a moving time window, averages the measurements in the moving window, determines whether the average has stabilized, and outputs an average temperature. A method of calculating a subject's temperature determines the temperature of a cold junction of the thermopile (40), looks up a bias, and slope of the thermopile (40) based upon the temperature of the cold junction, measures the output of the thermopile (40), calculates the subject's temperature based upon a linear relationship between the output and the subject's temperature. The linear relationship is defined by the bias, and the slope.
