We proposed the imaging-type two-dimensional Fourier spectroscopy that is the phase-shift interferometry
between the objective lights. The proposed method can measure the two-dimensional 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.
We proposed the imaging type 2-D Fourier spectroscopy that has the phase shifter on the Fourier
transform plane. The objective lights from the transmitted component and the scattered component of
the measurement object are dispersed on the different area of the Fourier transform plane. Thus, by
introducing the spatial filter, we can emphatically observe the spectral characteristics of the scattered
component light. And the spectral characteristics of the transmitted component and the scattered
component are separately analyzed. But to apply this proposed spectroscopy to biological membrane,
the transmitted light is also diffused by complex refractive index distribution of membrane. Hence, to
control the directionality of the diffused reflected light, we propose the modified illumination method.
By this proposed method, since the diffused reflected light form the diffracted light, we can control
the diffused light as diffracted light to apply for the biological membrane.
