    摘要: A picture generation apparatus includes at least a light source assembly, a spatial light modulation assembly, a beam adjustment assembly and a lens assembly. The light source assembly is configured to generate a first beam. The spatial light modulation assembly is configured to modulate the first beam to generate a picture beam. The lens assembly is configured to project the picture beam onto a projection surface to display a target picture. The beam adjustment assembly is disposed in the lens assembly or on an optical path between the light source assembly and the spatial light modulation assembly, and is configured to adjust a light amount of the first beam, to adjust brightness of the target picture.

    摘要: The present disclosure relates to an imaging apparatus and an imaging method that allow multi-spectral images to be taken at high speeds and in a reliable manner.The imaging apparatus includes an imaging element that takes an image of a subject, a multi-spectral filter that has a plurality of spectral filters dispersing incident light on the imaging element by predetermined wavelength regions, and a drive unit that drives the multi-spectral filter without stopping the individual spectral filters and continuously switches the spectral filters to cover an opening in the imaging element. In addition, the imaging apparatus detects whether a boundary between adjacent ones of the plurality of spectral filters included in the multi-spectral filter is in a position to block the opening in the imaging element, and performs signal processing for invalidating an image output from the imaging element in a period in which it is detected that the boundary between the spectral filters is in the position to block the opening in the imaging element. The present technology is applicable to an imaging apparatus that is capable of taking multi-spectral images, for example.

    摘要: Various embodiments may relate to a lighting device, including an excitation radiation source and a two-sided luminescent-material wheel. At least one luminescent material is provided on each of the two sides of the two-sided luminescent-material wheel, thus both on the front side and on the opposite back side. The luminescent materials on both sides are excited sequentially in time. For this purpose, at least one transmissive region is provided in the rotating luminescent-material wheel, through which transmissive region the excitation radiation can radiate, which excitation radiation can be deflected onto the luminescent material on the back side by means of an optical unit.

    摘要: A wavelength converting member includes at least a first, second, and third regions, circumferentially on a disc-shaped light-transmissive substrate. The first region includes, from a light incident direction, a first and second phosphor layers. The first phosphor layer includes a first phosphor to absorb at least part of incident light and to emit a first light having a wavelength different from the incident light. The first phosphor layer defines an indentation in a surface on the second phosphor layer side, with a depth a half or more of the thickness of a portion of the first phosphor layer absent of the indentation. The second phosphor layer includes a second phosphor to absorb at least part of the first light emitted by the first phosphor and to emit a second light having a wavelength different from the first light, and is disposed in the indentation of the first phosphor layer.
