    Abstract: A scanning optical apparatus includes a light source, a deflector and an imaging optical system. The deflector deflects a beam emitted from the light source to scan a scanning surface with the beam in a main scanning direction. The imaging optical system focuses the beam on the scanning surface. The imaging optical system includes a first lens having negative power in a sub scanning direction and a second lens having positive power in the sub scanning direction, in which the sub scanning direction is parallel to the scanning surface and perpendicular to the main scanning direction. The power φ1 of the first lens, the power φ2 of the second lens and a magnification β in the sub scanning direction of the imaging optical system satisfy the conditions −1.2≤φ1/φ2≤−0.9 and −1.3≤β≤−0.8.

    Abstract: A strain sensor includes a light source, a marker which is disposed on a measuring object so that light from the light source is reflected by or transmitted through the marker, a detector which detects the intensity of the light from the marker, and a signal processor which calculates a strain amount based on the detected light intensity. The marker is a flat film including first and second media having different refractive indexes. The second medium is periodically arrayed in the first medium and exists simultaneously with the first medium on a plane parallel to the marker mounting surface. The maximum length of the second medium in a direction parallel to the mounting surface is shorter than the wavelength of the emitted light. The first and second media deform in response to load in a direction parallel to the mounting surface.
