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 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.
