Abstract
1363702 Colour-coding lens array RCA CORPORATION 19 April 1971 [17 April 1970] 55376/73 Divided out of 1363701 Heading G2J Two arrays 22, 23 of cylindrical lens elements disposed in front of a television camera tube 17 have different refractive indices and are separated by an optical coupling means 24, which is in contact with the curved lens surfaces of the arrays 22, 23, the refractive index of optical coupling means 24 for blue light being equal to that of array 22, and its refractive index for red light being equal to that of array 23. The lens elements of array 22 are convex and parallel to alternate cyan and transparent stripes of one of two gratings of a filter 14, these stripes being at right angles to the direction of line scan of tube 17. The lens elements of array 23 are concave and parallel to oblique alternate yellow and transparent strips of the other grating of filter 14. Thus red light is encoded by the cyan – transparent grating of filter 14 and is found by lens array 22, but is unaffected by the boundary between lens array 23 and optical coupling means 24. Similarly blue light is encoded by the yellow – transparent grating and focused by lens array 23.
