    Abstract: PROBLEM TO BE SOLVED: To provide an optical waveguide-type RF optical converter which is compact and can be manufactured at a low cost, and to provide an optical modulation element. SOLUTION: The optical waveguide-type RF optical converter 1 includes a ring resonator 10 and a ferroelectric layer 13. The ring resonator 10 includes a ring-like optical waveguide 11 provided so as to be optically coupled to the optical waveguide. The ferroelectric layer 13 is provided so as to form a portion of the clad of the ring-like optical waveguide 11. When an electric field is applied from the outside to the ferroelectric layer 13, as the refractive index of the ferroelectric layer 13 is changed corresponding to the strength of the electric field, the effective refractive index of the ring-like optical waveguide 11 is changed as well. Since the filter characteristics of the ring resonator 10 are shifted to the short wavelength side or the long wavelength side by the change of the effective refractive index, the intensity of light is changed when the wavelength of light propagated through the optical waveguide-type RT optical converter 1 is in the shift range of the filter characteristics. In such a manner, RF signals are converted to light intensity signals. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a biometrics authentication system having a small and simple configuration and implementing both of biometrics authentication and position detection. SOLUTION: The biometrics authentication system 1 includes a near-infrared light source 10, a cover glass 11, a microlens array 12, a light-receiving element 13, an image processing section 14, an authentication section 15, a position detection section 16, a light source driving section 181, a light-receiving element driving section 182 and a control section 19.

Consequently, light-sensing data of the living body 2 is obtained. The image processing section 14 generates disparity image data, on the basis of the light-sensing data. The authentication section 15 performs biometrics authentication, on the basis of the disparity image data. The position detection section 16 performs position detection. The biometrics authentication and the position detection are performed by the same light source and detection optical system. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To manufacture a high-density optical master disk and a low-density optical master disk with the same exposure device. SOLUTION: Laser light emitted from a light source 1 becomes parallel light in a collimator lens 2 and then is made incident into an objective lens 4 through a beam splitter 3 and an optical element 9 for spot formation. The light is condensed by the objective lens 4, and a spot is formed on a master disk 5. An inorganic resist layer on the master disk 5 is exposed to the laser light from the objective lens 4. Spot sizes are changed between a high-density optical master disk and a low-density optical master disk by the optical element 9 for spot formation. When the low-density optical master disk is produced, the diameter of a spot is larger than that in the case of the manufacturing of the high-density optical master disk. An liquid crystal element or a magnification conversion element is used as the optical element 9 for spot formation. COPYRIGHT: (C)2006,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To enable stable operation without being affected by external environment. SOLUTION: A liquid crystal panel 1 gives a phase difference corresponding to a received electric signal to the transmitted light of a passing beam. A phase difference detecting means 2 detects the phase difference from the transmitted light. A phase difference control means 3 performs feedback control over the electric signal so that a target phase difference and a phase difference detected at the time of land reproduction, and a target phase difference and a phase detected in groove reproduction become equal respectively. An electric signal sending-out means 4 switches and outputs the corresponding electric signal at the time of land reproduction or groove reproduction under feedback control.

    Abstract: PROBLEM TO BE SOLVED: To reproduce data with the satisfied bit error rate even when the unexpected DC level change peculiar to the DWDD(domain wall displacement detection) system is generated in the reproduced signal. SOLUTION: This device is the data reproducing device utilizing the DWDD system for handling a magneto-optical recording medium consisting of a magnetic film with at least three layers such as a movable layer, switching layer and memory layer, and being constituted so that the size of the magnetic domain effectively recorded by the generation of the movement of the magnetic domain of a movable layer is expanded in the region where the temperature of the magnetic film becomes the Curie temperature of the switching layer or higher. The reproduced signal SMO is supplied to a detection circuit 157 of the movement of magnetic domain wall after equalizing the waveform by an equalizer circuit 156. By this detection circuit 157, the detection signal P DS for the generation of the movement of magnetic domain wall is produced by using a differential signal S11 of the reproduced signal SMO or a secondary differential signal S12 without being affected by the unexpected DC level change of the reproduced signal SMO. The data detection is executed by a data detection circuit 159 with the use of this detected signal PDS, then the reproduced data DP are outputted.
