Abstract
We proposed the imaging type 2-D Fourier spectroscopy that is the phase-shift interferometry between the objective lights. The proposed method can measure the 2-D spectral image only on the focal plane. We construct the proposed method by the infrared optical system to try to apply for the componential analysis of foreign particle and the noninvasive measurement of bio membrane. In this report, we overview the three research projects, the removal technology of foreign particle for the flat panel display, the spectral tomography of living single-cells and the prevention and early diagnosis measurement using light harmless to humans.
