    摘要: According to an embodiment, an optical inspection apparatus includes: an illumination portion, a wavelength selection portion and an imaging portion. The illumination portion irradiates a first object point of a surface of an object with first illumination light, and a second object point of the surface of the object with second illumination light. The imaging portion images light from the first object point through the wavelength selection portion when a normal direction at the first object point and a direction of the first illumination light have an opposing relationship, and images light from the second object point through the wavelength selection portion when a normal direction at the second object point and a direction of the second illumination light have an opposing relationship.

    摘要: According to one embodiment, an optical test apparatus includes a first aperture, a second aperture, an image sensor, and a first lens. The first aperture includes a first aperture plane provided with a first wavelength selecting region. The second aperture includes a second aperture plane provided with a second wavelength selecting region different from the first wavelength selecting region. The image sensor is configured to image a light beam passing through the first aperture plane and the second aperture plane and reaching an imaging plane. The first lens is configured to make a light beam passing through the first aperture plane and the second aperture plane be incident on the imaging plane.

    摘要: According to an embodiment, an optical apparatus includes a lighting unit, an imaging unit, and a processor. The lighting unit emits illumination rays. The imaging unit includes: a wavelength selecting unit including first and second wavelength selection regions; and a sensor. The first wavelength selection region converts a first ray passing through the first wavelength selection region into a first selected ray. The second wavelength selection region converts a second ray passing through the second wavelength selection region into a second selected ray. The sensor can acquire color phase information indicating color phases of the first selected ray and the second selected ray. The processor estimates a ray direction of the first ray and a ray direction of the second ray based on the color phase information and a relative position of the wavelength selecting unit in the imaging unit.

    摘要: According to one embodiment, an optics includes an incidence part, a first internal total reflection part, and an emission part. The incidence part is where a light beam enters. The first internal total reflection part internally totally reflects a light beam from the incidence part. The emission part emits light beam internally totally reflected by the first internal total reflection part. The first internal total reflection part includes a first ridge part. The first ridge part extends radially from a central axis of the optics. The cross-sectional shape of the first ridge part changes according to a distance from the central axis.

    摘要: According to one embodiment, an illumination device includes a plurality of light emitting elements and a plurality of reflectors. The plurality of reflectors include at least one first reflector and at least one second reflector. The first reflector is provided corresponding to the first region at the center and is provided so that the corresponding light emitting element is positioned within a focal region in the vicinity of a focal point. The second reflector is provided corresponding to the second region, has an angular eccentricity so as to collect light on one region on the optical axis, and is provided so as to be positioned within a margin region in which one of the corresponding light emitting elements is provided at a position farther away than a second focal region in the vicinity of the focal point.
