ProblemsTo provide a method for evaluating characteristics of MZ interferometers in an optical modulator having a plurality of MZ interferometers.Means for Solving ProblemsWhen an optical modulator includes a plurality of MZ interferometers, the 0-degree component contains a signal derived from an MZ interferometer other than the MZ interferometers for evaluating the characteristic. For this, it is impossible to accurately evaluate the characteristic of the MZ interferometers. The present invention does not use the 0-degree component normally having the highest intensity. That is, the characteristic of the MZ interferometers are evaluated by using a side band intensity of the component other than the 0-degree component.

摘要:
An object of the present invention is to provide a radio-on-fiber unit and a radio-on-fiber system which can transmit/receive signals at adequate rates especially, to/from a mobile device. A first aspect of the present invention relates to a radio-on-fiber unit (3) which includes an antenna array (1) and a light modulator array (2). The light modulator array (2) comprises antenna elements (5) and light modulators (7) that are connected with the respective antenna elements via electric circuits. The optical waveguide (13) is composed of linear optical waveguides (13) that are arranged along the light modulators (7) included in certain lines among the light modulators (7). The light modulator array (2) comprises reflection units (17) for connecting two adjacent linear optical waveguides with each other. Consequently, a signal light inputted to a light input unit (11) is outputted from a light output unit (15) via each linear optical waveguide (13).

摘要:
An audio feature is extracted from audio signal data for each analysis frame and stored in a storage part. Then, the audio feature is read from the storage part, and an emotional state probability of the audio feature corresponding to an emotional state is calculated using one or more statistical models constructed based on previously input learning audio signal data. Then, based on the calculated emotional state probability, the emotional state of a section including the analysis frame is determined.
摘要:
An optical measurement apparatus is provided for conducting a test by efficiently reading color development of a reagent after reaction by optical measurement.To the above end, an optical measurement apparatus is provided which is to be used with at least one test instrument mounted to the apparatus. The test instrument includes a carrier provided with at least one reagent retaining portion which retains a reagent, and a sample is applied to the carrier. The optical measurement apparatus includes a reader for reading color development of the reagent retaining portion, and a controller for performing driving control of the reader and determination. The controller performs the determination by utilizing data obtained by a reading operation P to read the color development of the reagent performed after the lapse of a reaction completion period Tr1-Tr6 from the mounting of the test instrument, and the reaction completion period depends on the reagent.
