Abstract:
The present invention provides a light-enhancing component and a fabrication method thereof by using the focused-ion-beam. In the present invention, the surface plasmon polariton structure is coated on the surface of the optical fiber so as to form the light-enhancing component. When the light passes through the optical fiber, the luminous flux transmitted through the aperture on the surface plasmon polariton is enhanced, and the light beam smaller than the diffraction limitation can be transmitted to the far-field, i.e. the nano-optic sword is formed. The light-enhancing component of the present invention can be used for the optical data storage, the optical microscopy, the biomedical detections and the lithography to perform the extra optical resolutions beyond the diffraction limitation.

Abstract:
An apparatus for improving decoding accuracy of an equalized signal having a direct current (DC) level obtained from an optical disk is provided. A Viterbi decoder is configured to decode the equalized signal and output a Viterbi-decoded signal. A DC controller is configured to adjust the DC level of the equalized signal such that the equalized signal with the adjusted DC level is decoded.
Abstract:
Disclosed herein is the use of an extract from an Aster species for the preparation of a medicament for the treatment of opioid-induced constipation. The extract is extracted from fresh and/or dried roots and rhizomes of a Tatarian aster (Aster tartaricus) plant, in which the extraction uses water or 40-95% (v/v) ethanol as an extractant to obtain an extraction mixture. In some embodiments, the extraction mixture is then eluted with water followed by at least one eluent.
Abstract:
The present invention relates to a monochromatic measurement system. The system mainly includes a monochromator, a light-detecting device and a filter device. The monochromator functions to split light under test into respective light beams with different wavelengths. The filter device modulates the transmission efficiency of the respective light beams, so that the wavelengths of the light beams to which the light-detecting device displays a better response have a lower transmission efficiency while the wavelengths of the light beams to which the light-detecting device displays a lower response have a higher transmission efficiency. The response values measured by the light-detecting device with respect to different wavelength intervals are normalized accordingly. The measurement errors attributed to the measurement precision of the instrument and the environmental noise are independent from the variation of wavelength. The reliability of the measurement instrument is elevated.
