Abstract: A projection device includes multiple optical fiber mounting mechanisms. Each of the optical fiber mounting mechanisms includes an optical fiber extending along a first direction as an axis direction, a signal circuit extending along the first direction, and a mounting structure. The optical fiber includes an engaging section. The mounting structure surrounds the engaging section of the optical fiber and the signal circuit. The mounting structure includes an installation portion extending radially relative to the first direction. The installation portion includes a surface and multiple elements exposed from the surface. The surface includes a normal direction parallel with the first direction. A first length of the engaging section of the optical fiber protruding from the surface of the installation portion is longer than lengths of the elements protruding from the surface.

Abstract: An optical actuator includes a base, a light-transmitting plate, a frame, a plurality of suspension members, and a plurality of actuation members. The base has a mounting surface. The light-transmitting plate is located above the mounting surface. The frame frames an outer edge of the light-transmitting plate. The frame retreats inwardly relative to the mounting surface, so that the mounting surface has a plurality of disposing areas relative to the frame. The suspension members are respectively located on the disposing areas and connected between the base and the frame. The actuation members are respectively located on the disposing area and configured to drive the frame to reciprocate relative to the mounting surface.

Abstract: An optical fiber mounting mechanism includes an optical fiber, a signal circuit, and a mounting structure. The optical fiber extends along a first direction. The signal circuit extends along the first direction. The mounting structure is disposed at ends of the optical fiber and the signal circuit. The mounting structure surrounds the optical fiber and the signal circuit. The mounting structure has an installation portion. The installation portion extends radially relative to the first direction as the axis direction. The installation portion has a plurality of elements. The elements are exposed from a surface of the installation portion. The surface has a normal direction parallel with the first direction.
