摘要： According to one embodiment, an optical imaging apparatus includes a polarizer assembly, a polarization image sensor, and a lens assembly. The polarizer assembly is configured to acquire a first light ray of a first polarization component and a second light ray of a second polarization component which is different from the first polarization component, by using a light flux from an identical direction. The polarization image sensor is located in a position facing the polarizer assembly. The polarization image sensor is configured to acquire an image of the first polarization component and an image of the second polarization component at once or at the same time. The lens assembly includes a first lens configured to form the images on the polarization image sensor.

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 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.

摘要： According to one embodiment, an optical test apparatus includes a photodetector and a processing circuit. The photodetector outputs, as a light receiving signal, information concerning a light direction of received light. The processing circuit processes the light receiving signal to acquire information concerning a standard light direction as a standard and information concerning a passing light direction of passed light which has passed through an object; compares the information concerning the passing light direction with the information concerning the standard light direction, and on the basis of results of the comparison, acquires information concerning internal physical quantities of the object.

摘要： According to an embodiment, a nozzle of an additive manufacturing device includes a first inner surface that defines a first path through which an energy ray passes; and a second inner surface that defines a second path that extends along the first path and through which gas and a powder material pass. The first path opens to a leading end of the nozzle. The second path opens to near or around the first path. At least part of the second inner surface includes a first region having a larger friction coefficient for the powder material than the friction coefficient of at least one of the first inner surface and an outer peripheral surface of the leading end.

摘要： According to one embodiment, a solar cell module includes a solar cell panel and a concentrator. The solar cell panel includes a solar cell. The concentrator reflects light incident from the outside and irradiates the light onto the solar cell. The concentrator has a first surface and a second surface. The first surface reflects light incident at a first incident angle and irradiates the light incident at the first incident angle onto a first portion within the area of the solar cell. The second surface reflects light incident at a second incident angle and irradiates the light incident at the second incident angle onto a second portion within the area of the solar cell. The second incident angle is different from the first incident angle. The second portion is different from the first portion. The first surface and the second surface are asymmetric as viewed from the solar cell.
