Optical projection grid, scanning camera comprising an optical projection grid and method for generating an optical projection grid

摘要

the invention relates to an optical projektionsgitter (1) for the production of a light distribution, and the projektionsgitter (1) has a transmissionsverteilung, with the transmissionsverteilung by parts (2a, 2b,...2i), translucent and opaque structures (5). trukturen (4), is formed.within a section (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2l) are distributed in several structures of any kind, essentially incoherent and each other alternately, with the ratio of translucent structures (5) opaque structures (4) within a buying empire (2a, 2b,...2i) chosen so that the strand is (2a, 2b,...21) associated transmissionswert (ta, tb,...ti) at least in a statistical way is achieved. the invention also relates to a messkamera with an optical projektionsgitter and a method for production of an optical projektionsgitters.
