Abstract: A micromechanical device includes a tiltable structure that is rotatable about a first rotation axis. The tiltable structure is coupled to a fixed structure through an actuation structure of a piezoelectric type. The actuation structure is formed by spring elements having a spiral shape. The spring elements each include actuation arms extending transversely to the first rotation axis. Each actuation arm carries a respective piezoelectric band of piezoelectric material. The actuation arms are divided into two sets with the piezoelectric bands thereof biased in phase opposition to obtain rotation in opposite directions of the tiltable structure about the first rotation axis.
Abstract: A scanning optical system, includes a mirror unit having a first mirror surface and a second mirror surface which incline to a rotation axis; and a light projecting system having a light source. A light flux emitted from the light source is reflected on the first mirror surface of the mirror unit, thereafter, reflected on the second mirror surface, and then, projected so as to scan in a main scanning direction onto an object in accordance with rotation of the mirror unit. In the case where a virtual plane is set in a range including the object, a light flux reflected on the second mirror surface has, upon entering the virtual plane, a cross sectional shape in which a length in a direction orthogonal to the main scanning direction is longer than a length in the main scanning direction.
Abstract: In an electro-optical device, a light-transmitting cover is disposed in mirrors, and when light is applied toward the mirrors through the light-transmitting cover, the temperature of the light-transmitting cover tires to increase due to the applied light. Here, in the electro-optical device, first metal portions that are in contact with the light-transmitting cover and the element substrate are formed. For this reason, it is possible to release the heat of the light-transmitting cover to a substrate through the first metal portions and the element substrate.

Abstract: Provided is an imaging apparatus including: an imaging unit; a display unit, through which at least a part of an imaging region of the imaging unit can be seen in a see-through manner and which is configured to display a stereoscopic image formed of a left eye image and a right eye image; a focal distance adjustment unit configured to adjust a focal distance of the imaging unit; and a display controller configured to generate the left eye image and the right eye image such that a display object indicating the focal distance is seen at a depth position corresponding to the focal distance and cause the display unit to display the left eye image and the right eye image.
Abstract: An apparatus of structured light generation is equipped with a light source and a lens unit. The lens unit is installed in a compact housing of the apparatus of structured light generation. Moreover, the lens unit constructed two different optical path lengths within the housing. By the lens unit, light beams from the light source are collimated and converted into linear light beams. The linear light beams are locally overlapped or globally overlapped. Consequently, the light beam from the light source is shaped into a linear structured light or a linearly-overlapped structured light for detection.

Abstract: Described is an arrangement for the transformation of laser radiation. A projection system for generating spatially modulated laser radiation includes an optical arrangement for transforming laser radiation, a field lens, a spatial light modulator and a projection arrangement. By means of the optical arrangement, incidental laser radiation in a first direction (E) is reflected on an aspherically curved, reflective surface in a second direction (R), where in a plane perpendicular to the first direction (E) the laser radiation has an inhomogeneous beam profile (GB1, G2) with a first beam axis (A) and a second beams axis (B) perpendicular to the latter, and the aspherical curvature is designed, during the reflection on the reflective surface, to transform the inhomogeneous beam profile of the laser radiation for the first beam axis (A) and/or the second beam axis (B) respectively into a homogenous top-hat beam profile (H).
Abstract: The embodiments described herein provide scanning laser devices that include a relay optic between scanning surfaces. In general, the relay optic is configured to reimage the laser beam reflecting from a first scanner onto the second scanner. Specifically, the relay optic is configured to reimage a laser beam reflected from over an angular range from a first scanning surface of a first scanner onto the scanning surface of the second scanner. This can effectively make the exit pupil of the scanners substantially coincident, and thus can reduce the exit pupil disparity between the scanners that would otherwise exist.
Abstract: Various embodiments of a multi-laser system are disclosed. In some embodiments, the multi-laser system includes a plurality of lasers, a plurality of laser beams, a beam positioning system, a thermally stable enclosure, and a temperature controller. The thermally stable enclosure is substantially made of a material with high thermal conductivity such as at least 5 W/(m K). The thermally stable enclosure can help maintain alignment of the laser beams to a target object over a range of ambient temperatures. Various embodiments of an optical system for directing light for optical measurements such laser-induced fluorescence and spectroscopic analysis are disclosed. In some embodiments, the optical system includes a thermally conductive housing and a thermoelectric controller, a plurality of optical fibers, and one or more optical elements to direct light emitted by the optical fibers to illuminate a flow cell. The housing is configured to attach to a flow cell.

The flywheel includes a lens arranged to allow the reflected light to pass therethrough; and a main body arranged to directly support the lens, or indirectly support the lens through a lens frame arranged to accommodate the lens therein. At least one of the lens and the lens frame is arranged radially outside of the main body. An upper surface of the main body is arranged to cross a light path along which the incoming light travels at a position axially overlapping with at least a portion of the light source.
Abstract: A scanning projector and method is provided that generates a feedback signal from at least one photodetector. In the scanning projector, a scanning mirror is configured to reflect laser light into an image region and an over scanned region. The at least one photodetector is configured to receive a portion of the reflected laser light impacting the over scanned region, and provides the feedback signal responsive to the received portion of light. This feedback signal can then be used to provide precise control of the scanning mirror.
