An optical projection grating, measuring camera with an optical projection grating and method for producing an optical projection grid

摘要

An optical projection grating (1) for generating a light distribution, wherein the projection grating (1) has a transmission process, with the transmission process division by partial regions (2a, 2b, .. 2i), the transparent structures (5) and opaque structures (4), characterized in that, within a partial area (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 21) are distributed a plurality of structures of any type, wherein the ratio of transparent structures (5) to opaque structures (4) within a partial area (2a, 2b, .. 2i) is selected in such a manner that the partial region (2a, 2b, .. 2i) is associated with the transmission value (t_a, T_b, .. T_i) at least in a statistical average, is reached and that the structures (4, 5) are individual pixels, each partial region (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i) from a perpendicular to a direction of travel (x) of the grid (1) running strips of one pixel width, wherein at a pixel within the smallest unit of a partial region (2a, 2b, 2c, 2d,..
