The measurement system includes a light engine operable to illuminate a first grating of an optical device. The light engine projects a pattern with a light from a light engine. The light engine projects a pattern to the first grating such that a metrology metric may be extracted from one or more images captured by a detector of the measurement system. The metrology metrics are extracted by processing the image. The metrology metrics determine if the optical device meets image quality standards."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Illumination system for AR metrology tool","description":"Embodiments described herein provide for light engines of a measurement system and methods of using the light engines.
