The multi-sensor apparatus further comprises one or more light sources configured to illuminate the test surface and a spatial light modulator. The spatial light modulator is placed in a light path between the one or more light sources and a measuring location of the multi-sensor apparatus and is configured to modulate light emitted from at least one of the light sources. The method comprises performing a measurement for determining an illumination intensity map of the test surface and a measurement for performing a height map of the test surface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for measuring a height map of a test surface","description":"A method for measuring a height map of a test surface having a varying reflectivity using a multi-sensor apparatus including a pre-scan sensor and a height measuring sensor is disclosed.
