摘要： An optical fiber thermometer system utilizing the laws of blackbody radiation includes a sensor responsive to the temperature within a region to be tested for transmitting light energy generated as a function of the temperature according to Planck's equation along an optical transmission line, and a detector responsive to the light energy for producing an electrical current. The current is amplified by a linear amplifier having provision for automatically controlling the gain of the amplifier, depending upon the magnitude of the input current, to reduce the dynamic range of the input current. The output of the linear amplifier is a voltage which is used by a signal processing network to yield an accurate indication of the temperature within the region to be tested by solving the Planck equation between two predetermined wavelengths representing upper and lower limits of an optical filter which filters light energy entering the detector.

摘要： A knock detector for an internal combustion engine includes an optical fiber thermometer that senses variations in heat flow within an engine cylinder. The optical fiber thermometer includes a black body emitter disposed inside the cylinder which is heated by combustion gases to provide an optical output. The optical output is converted to an electrical signal whose fourier components are analyzed to determine whether a knock condition exists.

摘要： 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.

摘要： A knock detector for an internal combustion engine includes a pair of optical fiber thermometers that sense variations in heat flow within an engine cylinder. Each optical fiber thermometer includes a black body emitter disposed inside the cylinder which is heated by combustion gases to provide an optical output. The optical output is converted to an electrical signal which is analyzed to determine the relative time of arrival of a flame front at each thermometer, from which may be determined the speed of travel of the flame front between the thermometers and thereby whether a knock condition exists.
