− 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(More)
Camera calibration is necessary for 3D reconstruction from uncalibrated images. Considerable efforts have been made to recover photorealistic models of the real world. In this paper, we propose a new camera calibration for 3D reconstruction using the Key-frame selection method from uncalibrated images. We select the essential Key-frame using the number of(More)
Spectroscopic measurement is being widely used for non-invasive blood sugar measurement in recent past. Imaging type two-dimensional spectroscopic tomography has been designed using wave front division interferometer. Variable phase filter, which has fixed mirror and movable mirror, has been used to introduce the phase shift between rays. Capability of(More)

− 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 2D spectral image at the limited depth. Because of the imaging optical system, the 2D spectral images can be measured in high spatial resolution. And in the depth direction, we can get the spectral(More)
