    • Thermographic apparatus intended in particular for diagnosing disturbances in circulation in the extremities of a patient, by recording the temperature distribution along a selected line extending from the ankle of a patient up to the thigh on both legs of the patient, whereafter any asymmetry in the two registered temperature profiles is used for the basis of a diagnosis. The apparatus comprises a temperature transducer (4), preferably an IR-detector, which is carried on one end of an extendable and retractable arm (6), so that the transducer can be moved manually along a selected line on the leg (2) of the patient. Coupled to the arm (6) is a position transducer (11) for generating an electric signal representative of the distance moved by the temperature transducer. The apparatus also includes a recorder (10) to which both the temperature signal and the position signal are transmitted and which is arranged to record the measured temperature profile simultaneously. This sequence can be repeated on the other leg of the patient, so that the recorder records both temperature profiles. The apparatus also includes a signal-processing unit (14a, 14b) in which the analogue temperature signals and position signals are converted to digital form and stored so that they can later be processed in a calculator part (14c) which calculates the difference between the temperatures in mutually corresponding locations on the two legs of the patient, whereby a temperature difference-position-relationship is obtained, which after being converted to analogue form can be transmitted to the recorder (10) and recorded thereby.

    • Temperature measuring apparatus using the material whose light transmittancy depends on temperature. This apparatus uses either light having a first wavelength at which the transmittancy depends on temperature when passing through a temperature sensor (9) and light having a second wavelength at which the transmittancy is constant with no relation to temperature, or two lights having first and second wavelengths at which the transmittancies change differently from each other depending on temperature. The ratio of the signal showing the intensity of the light of the first wavelength after passing through the temperature sensor (9), to the signal showing the intensity of the light having the second wavelength is obtained for measurement. Thus, it is possible to obtain a temperature measuring apparatus with high accuracy, since the output is not influenced even though the coupling efficiency between the optical fibers and the temperature sensor and the propagation losses in the optical fibers change. The invention is suitable for a temperature measuring apparatus with a low and middle temperaturerange in environments including high voltage, high magnetic fields, a chemical atmosphere, and others.
