摘要： Object detection and distance measurement using a scanning device is provided. The beam deflection device for light detection and ranging (LiDAR) includes a base, permanent magnets, a maglev reflector attached to the permanent magnets, and control coils mounted on the base. The maglev reflector may be configured to levitate due to an electromagnetic interaction of the permanent magnets and the control coils, and the control coils may consist of horizontal (H)-control coils defining a position of the maglev reflector in a horizontal direction and vertical (V)-control coils defining a position of the maglev reflector in a vertical direction.

摘要： Provided are a laser device and a method of transforming laser spectrum, which provide a laser frequency stabilization and significant narrowing a laser spectrum. A laser device includes at least one multiple longitudinal mode laser (L) for generating a laser light having a spectrum of multiple longitudinal modes; at least one high quality factor (high-Q) microresonator (M) optically feedback coupled to the at least one multiple longitudinal mode laser (L); and a tuner (TU) for tuning the spectrum of multiple longitudinal modes of the laser light. The laser device is configured to output an output laser light having an output spectrum with at least one dominant longitudinal laser mode each at a reduced linewidth of the dominant longitudinal laser mode. The laser device allows increasing an emission power of a narrow linewidth lasing without an additional amplification while keeping a compact size of a device with a limited number of optical elements.

摘要： Provided are an optical switch and an imaging system using the same. The optical switch includes an electrically controlled optical shutter configured to alternately pass and block light beams incident thereon; and a prism array comprising prisms separated from each other by a gap and configured to deflect the light beams that passed through the optical shutter by a predetermined deflection angle, and being positioned on the optical shutter, wherein the optical shutter is configured to operate in a first mode of operation in which the light beams incident towards the gaps between the prisms of the prism array are passed and the light beams incident towards the prisms are blocked and a second mode of operation in which the light beams incident towards the gaps between the prisms of the prism array are blocked and the light beams incident towards the prisms are passed.
