    Abstract: An optical element for resonating and reflecting incident light having a wavelength includes a periodic structure formed of protrusions and recessions. A period of the periodic structure is equal to or less than the wavelength of the incident light. The incident light having the wavelength is resonated and reflected by a resonance caused between the incident light and the protrusions and recessions. Widths of the protrusions are spatially changed.

    Abstract: A rotating apparatus includes a folded back elastically deformable portion including a first piezoelectric element for deforming a first elastically deformable portion and a second piezoelectric element for deforming a second elastically deformable portion, and the rotating apparatus rotates a movable portion around a predetermined rotation axis, by respectively applying first and second driving voltage signals to the first and second piezoelectric elements, to deform the first and second elastically deformable portions. First and second connection positions have a relationship of being relatively the same or symmetrical across all folded back structures. The first connection position is where a signal line of the first driving voltage signal and the first piezoelectric element are connected, and the second connection position is where a signal line of the second driving voltage signal and the second piezoelectric element are connected.
