The optical attenuation cover is configured to attenuate an intensity of light that passes through the optical attenuation cover based on a length of an optical path of the light through the optical attenuation cover. In some embodiments, the optical attenuation cover may be embodied as a physical barrier cover and include light-blocking structures. Additionally, in some embodiments, the illumination maker may include a diffusive or retro-reflective core rather than the light source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Technologies for enhancing contrast of an illumination marker","description":"An illumination marker includes a light source and an optical attenuation cover coupled to the light source.
