Definitions

  • FIG. 2 shows an embodiment of the spectrometer of the present invention.
  • the detection signal from the photodetector 22 is processed by a signal processing device (not shown).
  • Various optical information of the sample (circular dichroism, light dispersion, linear dichroism, linear birefringence) based on the same frequency component as the polarization modulation frequency and twice the high frequency component of the detection signal Is required.
  • the spectrum of the above optical information can be obtained by changing the wavelength of the monochromatic light from the spectroscope and performing the measurement. The specific procedure for these measurements may be performed in the same manner as in the past.

Abstract

Cette invention concerne un spectromètre assurant une spectrométrie précise d'un échantillon tel qu'un échantillon auto-organisateur, voir un échantillon de gel. Ce spectromètre se caractérise en ce qu'il comprend une partie photoémettrice qui émet une lumière monochromatique dont la longueur d'onde est prise dans une pluralité de longueurs d'onde pour balayage de longueurs d'onde, une partie de changement de chemin optique pour le changement du trajet optique de la lumière émise, une partie de modulation de polarisation de la lumière assurant une polarisation périodique de la lumière dont le trajet est changé, un plateau pour échantillon tournant horizontalement sur l'axe optique, et un capteur optique détectant la lumière transmise au travers de l'échantillon sur le plateau ; et en ce que la partie photoémettrice émet une lumière dans la direction horizontale, cette lumière qui voyage dans le sens horizontal étant déviée dans la direction verticale par la partie de changement de chemin optique et tombe verticalement sur le plateau d'échantillon tournant où se fait la mesure du spectre de l'échantillon.
