Abstract: A reflection type optical modulator is provided to obtain a sufficient extinction ratio by forming a non-reflective layer on a light input/output surface and forming a high-reflective layer on a surface opposite to the input/output surface. A reflection type optical modulator includes a waveguide(22), a non-reflective thin film(28), and a high-reflective thin film(29). The waveguide includes an absorbing layer formed on a substrate. The non-reflective thin film is formed on one surface of the waveguide and the high-reflective thin film is formed on the other surface. The reflection type optical modulator further includes a lens type optical fiber(32) which is formed on a region adjacent to the non-reflective thin film in order to perform a light inputting/outputting operation. The non-reflective thin film is formed by using TiO2 and SiO2. The high-reflective thin film is formed by using SiO2 and Si.

Abstract: An optical transceiver used in an RoF(Radio-over-Fiber) communication system is provided to mount both of an optical receiving device, an optical modulation device, and a patch antenna on one module, thereby reducing footprint of the optical transceiver which will be used in a base station in the RoF system. A first optical fiber(250) is a path for transmitting an optical signal from a telephone station to a base station. An optical receiving device(210) receives the optical signal transmitted form the telephone station to the base station through the first optical fiber, and converts the signal into an electric signal. A second optical fiber(252) is a path for transmitting the optical signal which is transmitted from the telephone station to the base station and passes through the optical receiving device. An optical modulation device(230) modulates an electric signal, inputted from the outside, to the optical signal transmitted through the second optical fiber. A third optical fiber(254) is a path for transmitting the optical signal, modulated by the optical modulation device, from the base station to the telephone station.

Abstract: The present invention relates to a laser radar system and a method for obtaining target images. The present invention comprises a light source, a light deflector, and a photo-detector. The light source radiates laser beams. The light deflector is positioned between the light source and a target. The light deflector enables the laser beams to be radiated in other positions of the target as time passes. The photo-detector detects the laser beams reflected from the target according to the radiation of the light deflector. The light deflector comprises a receiving light detection surface having a diameter (D_DA) which satisfies a formula (Sqrt(2) x P_RBS + 2 x D_RBS

Abstract: PURPOSE: A dynamic range 3D image system is provided to obtain a dynamic range higher than the range when a 3D image is obtained. CONSTITUTION: An HDR(High Dynamic Range) generating module(440) generates a signal which shows the saturation degree of the pixel signal based on pixel signals detected by a pixel detecting module. The HDR generating module couples the pixel signals. The HDR generating module obtains a dynamic range image. A gain control signal generating module(430) outputs an output signal based on the size of a signal which shows the saturation degree of the pixel signal. The output signal is for supplying a voltage necessary for a gain control terminal of an optical detector.
