Optical arrangement for head-up display, and angle-sensitive filter arrangement with micro-louvered grating

An optical arrangement for a head-up display at a deflection surface, wherein the optical arrangement;

• comprises:
• a projection unit configured to emit light along a beam path,
• one or more holographic optical elements arranged along the beam path, and
• a filter arrangement, which is arranged downstream proceeding from the one or more holographic optical elements-and which comprises a micro-louvered grating configured for angle-selective filtering of incident light.
