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 on the focal plane. We construct the proposed method by the infrared radiation optical system to try to apply for the noninvasive measurement of the blood glucose level. In this report, we discuss about the spectroscopy method to measure the vessel area of the proximal skin surface that is little affected by the diffusion cased by the biological membrane. The proposed method is constructed with Fourier spectroscopy with high wavenumber resolution. Therefore, the proposed method can measure spectroscopy of greenhouse gases and noxious fumes with narrowband width of spectral adsorption index. In this report, we mention the principle of the imaging-type 2-D Fourier spectroscopy and the development of the 2-D spectroscopic measurement for unstructured environment.
