Es kann sowohl in Abbildungs- als auch in Projektionssystemen auftreten, wobei die Kontrolle in Abbildungssystemen von besonders kritischer Bedeutung ist. Es gibt verschiedene Streulichtquellen, welche die Leistung eines optischen Systems beeintr\u00e4chtigen k\u00f6nnen. Eine h\u00e4ufige Ursache sind Lichtreflexionen an mechanischen Montagefl\u00e4chen innerhalb des Systems. Diese Reflexionen k\u00f6nnen von den Oberfl\u00e4chen abprallen, in den Abbildungs- oder Projektionsstrahlengang gelangen und unerw\u00fcnschte St\u00f6rungen verursachen.<\/p>\n<div class=\"insert_portfolio_outer_wrapper\"><h3>Lassen Sie sich von den Rayzeek Bewegungssensor-Portfolios inspirieren.<\/h3><p>Nicht das Richtige gefunden?

Wenn \u00d6ffnungen im Geh\u00e4use vorhanden sind, kann externes Licht in das System eindringen und die gew\u00fcnschte Lichtausgabe st\u00f6ren. Dar\u00fcber hinaus kann Streulicht durch Lichtstreuung an Staubpartikeln oder Fehlstellen auf den optischen Oberfl\u00e4chen des Systems entstehen. Diese Unvollkommenheiten k\u00f6nnen dazu f\u00fchren, dass Licht in ungewollte Richtungen gestreut wird, was zu unerw\u00fcnschten St\u00f6rungen im optischen System f\u00fchrt. Streulicht kann auch aus internen Quellen stammen, etwa wenn Elemente des Systems aufgrund ihrer eigenen Erw\u00e4rmung Licht emittieren, was insbesondere bei infrarotempfindlichen Systemen der Fall ist. Dadurch kann unerw\u00fcnschte Infrarotstrahlung in das System eingebracht werden, was die Genauigkeit und Qualit\u00e4t der Abbildung oder Projektion beeintr\u00e4chtigt.<\/p>\n\n\n\n<div class=\"wp-block-group glossary_faqs\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\"><h2 class=\"wp-block-heading\" id=\"h-frequently-asked-questions\">H\u00e4ufig gestellte Fragen<\/h2>\n\n\n<div class=\"wp-block-group glossary_faq\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group glossary_faq_q\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\"><h3 class=\"wp-block-heading\" id=\"h-what-is-it-called-when-you-see-glare-around-lights\">Wie nennt man es, wenn man Blendung um Lichter herum sieht<\/h3><\/div><\/div>\n\n\n\n<div class=\"wp-block-group glossary_faq_a\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"wp-block-paragraph\">Das Sehen von Halos um Lichter ist ein Ph\u00e4nomen, das als Beugung (Diffraktion) bekannt ist.
