    Abstract: Un monochromateur à accès sélectif est décrit. Ce dispositif ne contient pas d'éléments mécaniques et élimine la nécessité de balayer séquentiellement les longueurs d'ondes de la lumière contenue dans un spectre lumineux pour sélectionner une ou des longueur(s) d'ondes voulues dans le spectre. Le dispositif comprend des moyens de commutation de grande vitesse (16), permet de sélectionner simultanément des longueurs d'ondes et des largeurs de bande multiples, et possède la capacité de corriger la non-linéarité dans des prismes, causée par la dispersion non-linéaire ou de second ordre de la lumière.

    Abstract: In a detection apparatus, a linearly polarized light beam polarized in a polarizer (62) is converted by being transmitted through a Pockels cell (60), driven by an alternative voltage, into an alternative linearly polarized light beam and a circularly polarized light beam, which is transmitted through a sample solution flowing through a flow cell (68). The transmitted light beam is separated into two polarized light components, and an intensity thereof is measured to obtain a signal proportional to an angle of rotation by the sample solution. A signal corresponding to an angle of rotation caused by an optical rotary power of the sample solution is obtained by subtracting the signal obtained during irradiation of the circularly polarized light from the signal obtained during irradiation of the linearly polarized light. The sample solution (18) is infused into an optical path of the flow cell (68) under a condition where mean velocity is 0.5 to 5 m/sec.

    Abstract: An objective cell is irradiated with laser beam of a predetermined wavelength. Only Stokes light is selected out of detected light including reflected light and scattered light of the laser beam, and a Raman scattering spectrum is obtained by dispersion of the selected Stokes light. A transcriptome of the objective cells is estimated, based on the Raman scattering spectrum. It is preferable to estimate the transcriptome of the objective cells, based on N-dimensional Raman data obtained by dimensional reduction of the Raman scattering spectrum. This configuration only needs to irradiate the objective cell with the laser beam and does not require to destroy the objective cell. As a result, this enables the transcriptome of the cell to be estimated in a short time period without destroying the cell.

    Abstract: A polarimeter for measuring chirality of a material comprising an optical ring cavity comprising a plurality of reflective elements configured to promote bi-directional propagation of a laser beam within the cavity, a laser-emitting device configured to introduce a first input laser beam and a second input laser beam into the ring cavity, and a Faraday rotator and a phase compensator configured to suppress a birefringent background as the first and second laser beams pass through the ring cavity, wherein the plurality of mirrors, Faraday rotator, and phase compensator are configured such that light from the first and second laser beams passes through a chiral material located within the cavity a sufficient number of times for a measurement of optical rotary dispersion (ORD) and circular dichroism (CD) of light transmitted through the chiral material to be obtained. Particular implementations include monolithic ring cavities or microresonators or use of intra-cavity gain media.
