摘要： In an optical sensor, a light emission system emits an irradiated light of a linear polarization in a first polarization direction toward a surface of a target object having a sheet shape from an incident direction which is inclined with respect to a normal direction of the surface. A first light detection system includes a first light detector arranged on a first light path of a specular reflected light, which is emitted from the light emission system and is specularly reflected from the target object. A second light detection system includes a second light detector arranged on a second light path of a diffuse reflected light which is diffusely reflected from an incident plane on the target object. The second light detector receives second light passed by an optical element which passes a linear polarization component of a second polarization direction perpendicular to the first polarization direction.

摘要： An optical device includes at least one surface emitting laser device having a dielectric film for causing a central portion of a light emitting region to have a comparatively higher reflectivity than a peripheral portion; a light receiving element disposed, with respect to a first direction, on one side to the surface emitting laser device; and a transparent member disposed in a path of light emitted from the surface emitting laser device and configured to reflect a portion of the light toward the light receiving element as monitoring light. The central portion has shape anisotropy in which a width measured on a line extending in the first direction and passing through the center of the light emitting region is smaller than a width measured on a line extending in a second direction, which is perpendicular to the first direction, and passing through the center of the light emitting region.

摘要： In a surface emitting laser element, on an inclined substrate, a resonator structural body including an active layer, and a lower semiconductor DBR and an upper semiconductor DBR sandwiching the resonator structural body are stacked. A shape of a current passing-through region in an oxide confinement structure of the upper semiconductor DBR is symmetrical to an axis passing through a center of the current passing-through region parallel to an X axis and symmetrical to an axis passing through the center of the current passing-through region parallel to a Y axis, and a thickness of an oxidized layer surrounding the current passing-through region is greater in the +Y direction than in the +X and −X directions. An opening width of a light outputting section in the X axis direction is smaller than another opening width of the light outputting section in the Y axis direction.
