摘要： An optical amplifier amplifies a light signal inputted to an optical amplifier fiber and outputs an amplified light signal, by exciting the fiber with an excitation light. The optical amplifier can keep its output light level constant and stable and reduce the excitation light when the light inputted to the fiber is cut off, just by detecting the optical output level at a post-stage of the fiber. The optical amplifier comprises a first control circuit, a second control circuit and a selector circuit. The first control circuit amplifies the difference between a first predetermined voltage and an o/e-converted voltage of the optical amplifier fiber output light to output an amplified voltage. The second control circuit amplifies the difference between the o/e-converted voltage of the excitation light and a selected one of the first control circuit output voltage and a second predetermined voltage to output an amplified voltage and controls the excitation light based on the second control circuit output voltage. The selector circuit detects a change in the first control circuit output voltage and depending on the change, selects the first control circuit output voltage or a second predetermined voltage.

摘要： An OCT technique that permits tomographic observation of biological body parts that are difficult to restrain, and also provides a tomographic observation technique for the observation of a constrainable part that does not require constraint and thus removes a burden on the biological body. A wavelength-tunable light generator (wavelength-tunable light source) is employed as the light source of the optical coherence tomography device. The wavelength-tunable light generator has a wave number tunable range width of at least 4.7×10−2 μm−1 and an emitted-light frequency width of no more than 13 GHz, for example, and is capable of changing the wave number stepwise at wave number intervals of no more than 3.1×10−4 μm−1 and time intervals of no more than 530 μs.

摘要： It is an object to prevent the image quality deterioration of a moving image likely to include a plurality of the same consecutive images such as a movie video and an animation video due to the motion-compensated frame rate conversion (FRC) processing. An image displaying device is provided with an FRC portion (10) for converting the number of frames in an input image signal by interpolating an image signal to which a motion compensation processing has been given between the frames in the input image signal, a genre determining portion (14) for determining whether the input image signal is a predetermined genre, and a controlling portion (15). The FRC portion (10) includes a motion vector detecting portion (11e) for detecting a motion vector between the frames of the input image signal, an interpolating vector evaluating portion (11f) for allocating an interpolating vector between the frames based on the motion vector information, and an interpolating frame generating portion (102) for generating an interpolating frame from the interpolating vector. In the case that the input image signal is relating to a movie or animation, the control portion (15) set the motion vector detected by the motion vector detecting portion (11e) to zero-vector to make the motion compensation processing of the FRC portion (10) ineffective.

摘要： A chromatic dispersion compensator of present invention includes a high-refractive-index VIPA plate, a three-dimensional mirror, and a control unit. The high-refractive-index VIPA plate is made of a material such as silicon having a refractive index higher than that of optical glass and is able to output incident lights toward different directions according to wavelength. The three-dimensional mirror reflects the light of each wavelength emitted from the high-refractive-index VIPA plate, at a predetermined position and returns the light to the VIPA plate. The control unit controls a temperature of the high-refractive-index VIPA plate at a constant level while controlling the position of the three-dimensional mirror corresponding to a chromatic dispersion compensation amount. Thereby, larger chromatic dispersion can be compensated while a decrease in transmission bandwidth is suppressed.

摘要： An object of the present invention is to provide an extreme ultraviolet light source target which can emits extreme ultraviolet light with high emission efficiency. A solid target made of heavy metal or heavy-metal compound and having a density 0.5 to 80% that of the crystal density is used. When the target is irradiated with a laser beam, plasma of the heavy metal contained in the target is generated, and extreme ultraviolet light having a predetermined wavelength which corresponds to the kind of the heavy metal is emitted from the plasma. When the density of the target is made to be smaller than the crystal density as described above, space distribution of the density of the generated plasma can be controlled, and the region in which plasma absorbs energy of the laser beam overlaps the region in which the plasma emits the extreme ultraviolet light. Thus, emission efficiency can be improved, preventing energy loss. For example, in a case where the SnO2 target having a density 24% of the crystal density is used, the emission efficiency at around 13.5 nm wavelength is higher than in the case where a Sn crystal target is used.

摘要： The optical receiver includes: an optical input port for receiving WDM signals; a transmittable-wavelength-variable filtering unit which transmits, of the received WDM signals, a light signal in a predetermined transmittable wavelength bandwidth with a desired central wavelength of λi (i=1 to n: n is an integer number greater than 2); an optical output port which outputs the remaining light signals at wavelengths (λi) (k=1 to n; k≠i) untransmittable through the transmittable-wavelength-variable filtering unit; and a control unit which controls the central wavelength so that the level of the light signal passing through the transmittable-wavelength-variable filtering unit is the maximum. It is whereby possible to flexibly accommodate changes in number of channels combined in a WDM system, and to adaptively minimize ASE light leaking into the photoreceptor of the optical receiver even in a CWDM system with wide channel spacing.
