Abstract: An optical unit includes: a first diffraction grating where light from a light source enters; a second diffraction grating that generates interference light as a result of diffracted light rays emitted from the first diffraction grating entering the second diffraction grating; and an optical member including a pair of reflective surfaces that are parallel and opposite to each other, the optical member being configured such that the pair of reflective surfaces respectively reflect ±mth-order diffracted light rays that are diffracted light rays of a specific order among a plurality of orders of the diffracted light rays emitted from the first diffraction grating so as to guide the ±mth-order diffracted light rays to the second diffraction grating, where m is a natural number.

Abstract: A vibration sensor according to an embodiment includes a substrate, a convex member, and a piezoelectric element. The substrate includes a first principal surface and a second principal surface. The substrate transmits vibration. The convex member is fixed on the first principal surface. The piezoelectric element is disposed within a second fixing region on the second principal surface. The second fixing region corresponds to, in a planar view, a first fixing region of the substrate on which the convex member is fixed.

Abstract: In one aspect, a load cell includes an elastic body, first optical unit, second optical unit, detector, and computation unit. The first optical unit has a light source, a first diffraction grating on which light from the light source is incident, and a light-receiving unit. The first optical unit is fixed to a first end portion of the elastic body and arranged within a hollow portion of the elastic body. The second optical unit has a second diffraction grating on which diffracted light from the first diffraction grating is incident to generate interference light. The second optical unit is fixed to a second end portion of the elastic body and arranged within the hollow portion. The detector detects the interference light. The computation unit computes a relative displacement amount of the second diffraction grating relative to the first diffraction grating on the basis of a signal obtained by the detector.
