    • Light-splitting elements are arranged in at least two columns and two rows to form two pairs 1a, 1b and 1c, 1d. Each element splits incident light into light rays and makes them fall on a portion of a photosensing section right under itself and an adjacent photosensitive cell. The element 1a splits the incident light so that a primary color ray C1 and its complementary color ray C1′ enter an adjacent cell 2b and an underlying cell 2a, respectively. The element 1b makes a primary color ray C2 and its complementary color ray C2′ enter an underlying cell 2a and an adjacent cell 2a, respectively. The element 1c does the same as the element 1b. And the element 1d makes a primary color ray C3 and its complementary color ray C3′ enter an adjacent cell 2c and an underlying cell 2d, respectively. These photosensitive cells 2 perform photoelectric conversion, thereby outputting an electrical signal representing the intensity of the incident light. By carrying out simple calculations between the outputs of these cells, a color signal and a luminance signal are generated.
    • 光分离元件以至少两列和两列排列以形成两对1a,1b和1c,1d。 每个元件将入射光分成光线并使它们落在其本身正下方的光敏部分的一部分和相邻的感光单元上。 元件1a分割入射光,使得原色光线C1及其互补色光线C1'分别进入相邻的单元2b和下面的单元2a。 元件1b使原色光线C2和它的互补色射线C2'分别进入下面的单元2a和相邻单元2a。 元件1c与元件1b相同。 并且元件1d使原色光线C3和其互补色光线C3'分别进入相邻单元格2c和下面的单元格2d。 这些感光单元2进行光电转换,从而输出表示入射光强度的电信号。 通过在这些单元的输出之间进行简单的计算,生成彩色信号和亮度信号。

    • There is provided an apparatus for performing, by optical code division multiplex access, at least one of encoding and decoding of wavelength-division-multiplexed light. The apparatus includes: an optical input/output section 203 for handling input/output of the wavelength-division-multiplexed light; and N fiber gratings (where N is an integer equal to or greater than two) 101 to 103, which are in a series connection to the optical input/output section 203. Each of the N fiber gratings has a sampled grating structure having an alternating array of first regions (11 to 14; 21 to 24; and 31 to 34) which provide a refractive index modulation with a relatively large amplitude and second regions (201) which provide a refractive index modulation with a relatively small amplitude, the first and second regions being disposed with a constant period P. Each sampled grating structure defines a plurality of reflection wavelength bands which are replicated with a period that is equal to the interval (ΔT) between the central wavelengths of wavelength bands contained in the wavelength-division-multiplexed light. The central values of the respective reflection wavelength bands differ from one fiber grating to another at least during operation.
