摘要： An interleaver is provided with an optical system configured to split light having traveled from a first port to a half mirror, into two beams and direct the beams toward first and second reflectors, respectively. Light reflected by the first reflector and arrived at the half mirror is split into two beams and directed toward second and third ports, respectively. Light reflected by the second reflector and arrived at the half mirror is split into two beams directed toward the second and third ports, respectively. An etalon filter configured to cause a loss on either one of light incident thereto from the first port and the beams directed toward the second port and toward the third port.

摘要： The first reading beam identical to the first reference beam and the second reading beam conjugate to the second reference beam are simultaneously applied to a hologram recording medium 1, on which holograms 2 and 3 have been recorded. A hologram is formed by interference between the first beam reproduced from the first reading beam and the second reading beam. Another hologram is formed by interference between the second beam reproduced from the second reading beam and the first reading beam. These holograms are recorded and superposed on the original holograms 2 and 3, thereby reproducing the original holograms 2 and 3.

摘要： The number of light sources and the number of divided light beams are optimized, so that a light beam with sufficiently reduced speckle contrast can be used as illuminating light. In an optical system for forming an image through a spatial modulator, laser light having a spectrum width of wave number and emitted from N (N is an integer not less than 1) light sources is guided to a fiber bundle so that the light is divided into M light beams (M is an integer not less than 2), a light path length difference of not less than a coherent distance is given to the respective light beams, and then, light axes are again aligned with each other to illuminate the spatial modulator, and when the light path length difference from one point on the spatial modulator to an image corresponding thereto has a standard deviation &sgr;Z, the number M and the number N are set so that a relation expressed by the following expression A is satisfied: ( numerical ⁢ ⁢ expression ⁢ ⁢ 49 ) ⁢ ⁢ NM · 1 + ( 2 · W · σ z ) 2 4 ≧ 1 Expression ⁢ ⁢ A

摘要： Barium sulfate having a specific crystal structure and optical characteristics is disclosed. The crystals have a plate-like structure of which the aspect ratio is 5-100 and the ratio of the square of the circumference of the plate and the area of the orthogonal projection plane is 20:1-150:1. In a preferred embodiment, a thin film of 25 .mu.m thickness with 20% by weight of the barium sulfate powder concentration has a scattering transmittance of 70% or greater and a total transmittance of 85% or greater. The cosmetic compositions to which the barium sulfate is incorporated exhibits excellent extendibility and adhesion to the skin and can effectively hide the spots or freckles on the skin. The cosmetic composition satisfies both the fine naked skin feeling and the skin covering effect, which have never been satisfied by conventional cosmetic compositions.
