Abstract: The present invention pertains to a device for measuring a temperature distribution, which can measure a temperature distribution without contacting a minor sample having a three-dimensional structure. More particularly, the device for measuring the temperature distribution can measure a three-dimensional temperature distribution for a sample, wherein the temperature distribution in a depth direction (direction z) of the sample is measured by a thermo-reflectance technique using a chromatic dispersion lens, a diffraction spectrometer and an optical detection array; and the temperature distribution in parallel directions (direction x-y axes) of the sample is measured by the thermo-reflectance technique using a biaxial scanning mirror.

Abstract: The present invention relates to an image sensor comprising a microlens array, and to a manufacturing method thereof. The method of the present invention includes gradually increasing the aluminum composition ratio of a compound semiconductor as the latter gradually gets farther from a substrate, to enable a microlens-forming layer to grow, and making the oxidation rate of the region adjacent to the substrate slower and the oxidation rate of the region farther from the substrate faster, making the interface between the oxidized region and the unoxidized region into a lens shape after the completion of oxidation. The thus-made lens is integrated into an image sensor. The present invention reduces costs for manufacturing image sensors in which a microlens is integrated, increases the signal-to-noise ratio and resolution of the image sensor, and achieves improved sensitivity.

Abstract: Provided is an imaging system which includes an optical fiber array probe unit integrated with an endoscope unit, thereby simultaneously measuring structural information and functional information of a sample.
