    Abstract: A two-dimensional scanner consists of a rotatable gimbal structure with vertical electrostatic comb-drive actuators and sensors. The scanner's two axes of rotation may be controlled independently by activating two sets of vertical comb-drive actuators. The first set of vertical comb-drive actuator is positioned in between a outer frame of the gimbal structure and the base, and the second set of vertical comb-drive actuator is positioned in between the inner part of the gimbal structure and the outer frame of the gimbal structure. The inner part of the gimbal structure may include a reflective surface, and the device may be used as a mirror. Furthermore, the capacitance of the vertical comb-drives may be measured to monitor the angular position of the mirror, and the capacitive position-monitoring signal may be used to implement closed-loop feedback control of the mirror angle. The two-dimensional scanner may be fabricated in a semiconductor process. Two-dimensional scanners may be used to produce fiber-optic switches.

    Abstract: A micromachine and a manufacturing method are provided for a micromachine that has a dynamic first microstructured portion serving as a drive portion, and a static second microstructured portion adapted to perform a switching function and which functions as an optical element. The second microstructured portion can be manufactured at least without complex steps, such as a silicon process, by forming a static second microstructure on the dynamic first microstructured portion, or in such a way as to be overlaid thereon by mold transfer. Thus, the microstructured portion of a complex shape can be easily formed with good reproducibility. When a plurality of elements are arranged in an array, similarly as in the case of a spatial light modulator, the stable reproduction thereof is achieved by the mold transfer. Thus, as compared with the case of manufacturing all elements in a silicon process, the probability of an occurrence of a defect is very low.

    Abstract: A low-voltage electromechanical device including a tiltable microplatform, method of tilting same and array of such devices are provided. The tiltable or steerable microplatform utilizes a bent-beam actuator to achieve large tilting angles with low actuation voltages. Thin beams of the actuator are bent in such a way as to cause the microplatform to pivot around a dimple support that generates a torsional force leading to angular motion in suspension beams attached perpendicular to the thin beams and, in turn, leading to angular or tilting motion in the suspended microplatform. Some of the key features include (1) the low-voltage bent-beam actuator; (2) a dimple-supported microplatform with a hole underneath in the substrate to allow light to pass through and to allow unhindered tilting of the microplatform; and (3) a method for constructing a microprism on the tiltable transparent microplatform for color dispersion purposes in an adaptive vision system.
