In an optical device, a base and a movable unit are constituted by a semiconductor substrate including a first semiconductor layer, an insulating layer, and a second semiconductor layer in this order from one side in a predetermined direction. The base is constituted by the first semiconductor layer, the insulating layer, and the second semiconductor layer. The movable unit includes an arrangement portion that is constituted by the second semiconductor layer. The optical function unit is disposed on a surface of the arrangement portion on the one side. The first semiconductor layer that constitutes the base is thicker than the second semiconductor layer that constitutes the base. A surface of the base on the one side is located more to the one side than the optical function unit.

Embodiments of the present disclosure relate to mount apparatuses for digital micromirror devices of digital lithography systems and methods of mounting the digital micromirror devices. The mount apparatuses described herein retain spatial light modulators, such as DMDs. The mount apparatus enables the flattening of the DMD by providing a force such that the pair of contact pads contact the DMD. The DMD is positioned in a mounting frame of the mount apparatus. Contact pads of the mounting frame are operable to apply pressure to the DMD.

A vehicular exterior rearview mirror assembly includes a mounting arm and a mirror head at one end of the mounting arm distal from an attachment portion of the mounting arm that is configured for attachment at a vehicle. A mirror reflective element is fixedly attached at the mirror head. An innermost side of the mirror reflective element is attached at a front side of an attachment plate. The mirror reflective element moves in tandem with movement of the mirror head relative to the mounting arm when the driver of the vehicle operates an electrically-operable actuator. The attachment plate includes wall structure that extends from the front side of the attachment plate and circumscribes and spans the perimeter circumferential edge of the glass substrate and does not encroach onto and does not overlap the front surface of the glass substrate of the exterior mirror reflective element.

A magnetically-actuated laser beam control assembly may include a magnetically permeable cover arranged to sealingly couple to an optics housing to cover an opening of the optics housing, an interior sub-assembly, and an exterior sub-assembly. The interior sub-assembly may include includes a linkage having a first section and a second section; the first section of the linkage to receive an optical component; and a ferroelectric or ferromagnetic material on the second section of the linkage. The exterior sub-assembly may include an electromagnet energizable to impart a magnetic force to the ferroelectric or ferromagnetic material to move the optical component from one of a resting position and a different position to the other of the resting position and the different position to cause the optical component to selectively optically process a laser beam. Other embodiments may be disclosed and/or claimed.

A system for outputting partially spatially coherent light to an imaging system is disclosed herein, which includes a spatially coherent light source configured to output a spatially coherent signal, at least one optical device having an optical device body with a first device surface formed thereon and configured to reflect a portion of the spatially coherent signal to form at least one coherent reflected signal. The optical device body also includes a second device surface having one or more surface irregularities configured to diffuse a portion of the spatially coherent light source output signal transmitted through the optical device body, to produce at least one spatially incoherent signal. The combination of the coherent reflected signal and the spatially incoherent signal form the partially spatially coherent light signal.

A vehicular frameless interior rearview mirror assembly includes a mirror head and a mounting portion. The mirror head includes a mirror reflective element and a mirror casing. The mirror reflective element includes a glass substrate having a planar front side and a planar rear side. No portion of the mirror casing overlaps the planar front side of the glass substrate of the mirror reflective element. A camera is disposed within the mirror casing. With the mounting portion of the mirror assembly mounted at an in-cabin side of a windshield of a vehicle, the camera views a driver of the vehicle, and when the mirror head is moved by the driver of the vehicle to adjust the rearward view provided by the mirror reflective element to the driver, the camera moves in tandem with movement of the mirror head. The camera is part of a driver monitoring system of the vehicle.
