<p><P>PROBLEM TO BE SOLVED: To provide a spectrometer for non-invasively and accurately measuring biogenic substances, and also to provide its method. <P>SOLUTION: Scattered light and transmitted light radially emitted in various directions from one bright spot within the palm S of a hand enter an objective lens 12, pass therethrough, and then arrive at a fixed mirror part 15 and a movable mirror part 16, separately, of a phase shifter 14. The light is reflected by the mirror parts 15 and 16, respectively, and then forms an interference figure on an imaging surface of a detection part 24 through an image-forming lens 22. Moving the mirror part 16 in such a state causes the intensity of interference light to gradually change on the imaging surface of the detection part, providing a waveform of an imaging intensity change (interference light intensity change) called an interferogram. By Fourier-transforming this interferogram spectral characteristics, or wavelength-by-wavelength relative intensities, of the scattered light and transmitted light, are acquired. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
