| Outline of Final Research Achievements |
Radiometric temperature measurement by incoherent digital holography was proposed. In the proposed method, the temperature measurement is performed with the reconstructed image of a thermal radiation based on radiation thermometry. For this measurement, radiance must be derived from a reconstructed image of a digital hologram. The relationship between a reconstructed image and its radiance was derived. The incoherent holography setup for the acquisition of a radiance from a reconstructed image was also proposed. With this setup, the holographic temperature measurement was performed. The temperature measurement of objects located at different distances was verified.

| Academic Significance and Societal Importance of the Research Achievements |
インコヒーレントホログラフィの新たな応用分野を開拓した．ホログラムの記録後にフォーカスの位置を変更できるので，奥行き方向に形状に変化のある物体や立体的に移動する物体の温度計測に有効である．例えば，生体やガス中粒子の温度分布計測などへの適用が考えられる．
