In comparison with this, the present invention addresses the problem of providing an apparatus for reducing scattered light influences on an intensity and/or phase determination of the intensity modulation of an intensity-modulated electromagnetic radiation signal. In order to solve this problem, the invention proposes configuring the apparatus of the type mentioned at the outset in such a manner that said apparatus has at least one scattered light reference pixel, which is arranged outside an imaging section of the imaging optics and is set up in such a manner that said pixel records measured values for an intensity-modulated scattered light signal during operation, and a determination device which is set up in such a manner that said determination device processes measured values from at least one pixel in a pixel matrix of the detector inside the imaging section as a first data input and measured values from at least one scattered light reference pixel as a second data input during operation in such a manner that said determination device determines a corrected intensity of the intensity-modulated radiation signal and/or a corrected relative phase between the intensity modulation of the intensity-modulated radiation signal and a reference signal at least for the pixel inside the imaging section and provides said intensity and/or phase as a data output."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Scattered light reference pixel","description":"The present invention relates to an apparatus for determining an intensity and/or a phase of intensity modulation of an intensity-modulated electromagnetic radiation signal, having a detector and imag","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9678200","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
