摘要: The invention describes a cathode ray tube in which the position of the electron beam (7, 8, 9) is determined in that detection strips (12, 13) are arranged between or below the individual phosphor strips of the phosphor layer (11). The detection strips (12, 13) each comprise a semiconductor component which amplifies the measured current signal. This renders the position determination of the electron beam (7, 8, 9) more definite and reproducible.

摘要: A light-collimating system for collimating light from a light source has a plurality of elements (2, 2′, . . . ), each element including at least a first wall (3, 3′, . . . ) and at least a second wall (4, 4′, . . . ). The first (3) and second wall (4′) of adjacent elements are spaced with respect to each other at a side of the light-collimating system facing the light source, the spacing defining an aperture window (5, 5′, . . . ) for admitting light into the light-collimating system. The first and second wall of said adjacent elements form a wedge-shaped structure widening in a direction facing away from the light source. The first and the second wall are provided with a specular reflecting surface at a side facing the wedge-shaped structure. According to the invention, the wedge angle (w of the first and second wall with respect to the normal on the aperture window are adjustable for enabling adjustable collimation.

摘要: A light-collimating system for collimating light from a light source has a plurality of elements (2, 2′, . . . 12, 12′, . . . ). Each element includes a first wall (3, 3′, . . . ; 13, 13′, . . . ) and a second wall (4, 4′, . . . ; 14, 14′, . . . ). The first wall and the second wall of each element are spaced with respect to each other. The first wall (3; 13) of an element (2; 12) and the second wall (4′; 14′) of an adjacent element (2′; 12′) form a wedge-shaped structure widening in a direction facing away from the light source. The first and second wall are at a side facing the wedge-shaped structure provided with a specular reflecting surface. Preferably, the space formed between the first and second wall of each element and the supporting member is provided with a specular and/or diffuse reflecting material.
