Abstract: A system includes: a light source; first and second gratings; and at least one reflective component that in a first position forms a first light path originating at the light source and extending to the first grating and thereafter to a subsequent component in the system, and that in a second position forms a second light path originating at the light source and extending to the second grating and thereafter to the subsequent component.

Abstract: An optical mount has a component support for an optical component, a clamp member and a frame. The frame has a component support interface that, when positioned against the component support, defines a first spherical curvature for pivoting the component support about a center of curvature. A clamping interface defines a second spherical curvature, concentric with the center of curvature of the component support interface, for pivoting the clamp member. A coupling is configured to urge the clamp member toward the component support against the frame.

Abstract: An optical shutter apparatus has a shutter blade pivotable between first and second positions. The shutter blade in the first position blocks at least a portion of a light path. A stepper motor pivots the shutter blade to first or second positions. A magnetic shutter blade retention apparatus has a first movable member with a first surface, coupled to the shutter blade. A first stationary member is spaced apart from the shutter blade and is magnetically attracted to the first stationary member when the stepper motor is de-energized. When the shutter blade is pivoted to the first position, a point on the first surface is spaced apart from the first stationary member by a first distance; when the shutter blade is pivoted to the second position, the point on the first surface is spaced apart from the first stationary member by a second distance that is less than the first.

Abstract: A MEMS scanning device includes more than one type of actuation. In one approach capacitive and magnetic drives combine to move a portion of the device along a common path. In one such structure, the capacitive drive comes from interleaved combs. In another approach, a comb drive combines with a pair of planar electrodes to produce rotation of a central body relative to a substrate. In an optical scanning application, the central body is a mirror. In a biaxial structure, a gimbal ring carries the central body. The gimbal ring may be driven by more than one type of actuation to produce motion about an axis orthogonal to that of the central body. In another aspect, a MEMS scanning device is constructed with a reduced footprint.
