    Abstract: There are provided an optical non-destructive inspection apparatus and an optical non-destructive inspection method, which can inspect a measurement object such as a wire bonding portion in a broad measurable temperature range in a short time, with high reliability. The apparatus includes a focusing-collimating unit (10), a heating laser beam source (21), a heating laser beam guide unit, an infrared detector (33), an emitted-infrared guide unit, first and second correcting laser beam sources (22, 23), first and second correcting laser beam guide units, first and second correcting laser detectors (31, 32), first and second reflected laser beam guide units, and a control unit (50). The control unit (50) controls the heating laser beam source (21) and the first and second correcting laser beam sources (22, 23), measures a temperature rise characteristic that is a temperature rise state of a measurement spot (SP) based on a heating time, on the basis of a detection signal from the infrared detector (33) and detection signals from the first and second correcting laser detectors (31, 32), and determines a state of a measurement object (bonding structure (97)) based on the measured temperature rise characteristic.

    Abstract: The method is meant for the evaluating of the amount of micro and macro cracks in the pavement of a traffic lane, such as a road or street. The colder water beneath the pavement is under the load of heavy traffic pumped into the micro and macro cracks in the pavement and lowers the temperature of the pavement, so a large difference between the temperatures in different points on the pavement reveals a large amount of cracks. In the method, the examination span of the traffic lane is first selected. Thereafter the temperature T1 of the heavily loaded part of the pavement of the selected examination span and the temperature T2 of the lightly loaded part of the pavement of the same examination span are determined. A difference AT between the determined temperatures is calculated, which difference is compared to a reference value. If the difference is larger than the used reference value, the pavement lets through a significant amount of water. If the difference is smaller than the used reference value, the condition of the pavement is sufficiently good. The temperatures t r of the heavily loaded part of the pavement are measured at the wheel ruts and the temperatures t k of the lightly loaded part of the pavement are measured in the area outside the wheel ruts. The temperatures of the pavement are measured with an apparatus, which is placed in a vehicle travelling on the traffic lane. Alternatively the emissivity ε r of the heavily loaded part of the pavement and the emissivity ε k of the lightly loaded part of the pavement can be determined and the difference Δε can be compared to a reference value.

    Abstract: The method of contactless measuring the surface temperature and/or the emissivity of objects on the principle of scanning the infrared radiation coming out of the measured object (1) by means of, at least, two infrared radiation detectors (3,5). The particular infrared radiation detectors (3,5) are maintained at the different mean temperatures (T₁, T₂) by the supply of heat, while the different and independent output signals (U₁, U₂) of these detectors are obtained for the determination of surface temperature (T o ) and/or the emissivity of measurd object (1).

    Abstract: A method of determining true temperatures of a heated target material by its radiation is based on prior knowledge of an emissivity function. This function describes the relationship between the two spectral emissivities for the target material. The method comprises the steps of measuring two radiances corresponding to said spectral emissivities from the target material, assuming a temperature of the target material, then calculating a pair of emissivities which satisfy the emissivity function whereat the assumed temperature is the true temperature of the target material.

    Abstract: 1. Method for the contactless radiation measurement, independently of emissivity, of the temperature of an object, in which method beam densities or intensities are detected in several wavelength ranges in the visible or infra-red part of the spectrum and a radiation/wavelength curve is obtained from a series of at least two beam densities or intensities through iterative calculation with the aid of Planck's law of radiation, characterised thereby, that the curve most similar to this curve is sought with the aid of Planck's law of radiation as sum of the beam density (intensity) of a radiator at the temperature and with the emissivity of the object and of the beam density (intensity) of a radiator at the temperature of the environment, reflected at the object with the reflectivity (rho = 1 - epsilon, epsilon emissivity) and that the temperature, which corresponds to the Planck's curve found for the object, is determined as the true temperature of the object.
