| Outline of Final Research Achievements |
A method has been developed to obtain spectrally decomposed three-dimensional images for usual polychromatic objects under illumination of natural light. The method uses interferometric measurement and signal processing only. Theoretical analysis gives an impulse response function defined over four-dimensional space that determines simultaneously three-dimensional imaging property and spectral resolution of the method. A new criteria to estimate depth resolution of coherent and incoherent holographic techniques are also given.
