    • A method for finding a dip angle in a tilt-compensated electronic compass. The method finds a dip angle suitable for current environments to calculate a more accurate azimuth angle when measuring an azimuth angle of the tilt-compensated electronic compass. The method for finding an optimal dip angle in a prescribed environment using an electronic compass containing a two-axis geomagnetic sensor includes the steps of: a) setting a predetermined azimuth angle indicative of a horizontal status of a geomagnetic sensor to a reference azimuth angle; b) if the electronic compass is slightly tilted on the basis of the reference azimuth angle, stepwise-increasing a dip angle within a predetermined dip angle search range, and calculating azimuth angles associated with individual dip angles; c) comparing the calculated azimuth angles with the prescribed reference azimuth angle, and finding one azimuth angle, which is the closest to the reference azimuth angle, from among the calculated azimuth angles; and d) setting the dip angle applied to the found azimuth angle to a specific dip angle associated with a corresponding azimuth angle, such that a more accurate azimuth angle can be detected by the tilt-compensated electronic compass containing a two-axis geomagnetic sensor on the basis of the calculated dip angle.

    • Provided is a wavelength tunable optical filter of a micro-electro-mechanical system (MEMS). The wavelength tunable optical filter comprises two optical fibers or optical waveguides having their optical axes aligned to each other, two lens for collimating light at leading ends of the optical fibers or optical waveguides, two or more mirrors formed on a substrate, thermal actuators supporting at least one of the mirrors, wherein one of the mirrors is actuated by thermal expansion of the actuator. Because all mirrors are formed on a substrate, a manufacturing process is simple and an initial resonance wavelength can be precisely adjusted. Since the thermal expansion is generated by the electrical current directly flowing through the thermal actuators, it can be actuated by a low consumption power. Also, since an electrostatic force is not used to move the mirrors, a sticking phenomenon between the mirrors does not occur, and the wavelength can be tunable in a wide range. Since the planar mirrors are arranged in parallel, the light alignment is easily performed, the line width is constant and the insertion loss is low.
    • 提供了微机电系统(MEMS)的波长可调光滤波器。 波长可调光滤波器包括两个光纤或光波导,其光轴彼此对准,用于准直光纤​​或光波导前端的光的两个透镜,形成在基板上的两个或更多个反射镜,支持在 至少一个反射镜,其中一个反射镜由致动器的热膨胀致动。 因为所有的反射镜都形成在基板上,所以制造工艺简单,可以精确调节初始共振波长。 由于热膨胀是由直接流过热致动器的电流产生的,因此可以通过低功耗来致动。 此外,由于不使用静电力来移动反射镜,所以不会发生反射镜之间的粘附现象,并且波长可以在宽范围内可调。 由于平面镜平行配置,因此容易进行光对准,线宽恒定,插入损耗低。
