The present work employed a hybrid of the optical-transfer matrix and ray-tracing method to faithfully replicate complete physical imaging processes throughout a focusing schlieren optic system. A direct numerical simulation of a hypersonic boundary layer flow was employed to synthesize focusing schlieren images. The influence of various configuration parameters on the properties of focusing schlieren image such as local schlieren structure, brightness, sensitivity, and depth of field were systematically explored. In addition, an approximation method was proposed as a simplified means to facilitate the simulation of a focusing schlieren image.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380869859565483267","@type":"Researcher","foaf:name":[{"@value":"Mingjia Chen"}]},{"@id":"https://cir.nii.ac.jp/crid/1380869859565483268","@type":"Researcher","foaf:name":[{"@value":"Bing Liu"}],"jpcoar:affiliationName":[{"@value":"Northwestern Polytechnical University"}]},{"@id":"https://cir.nii.ac.jp/crid/1380869859565483264","@type":"Researcher","foaf:name":[{"@value":"Fei Qin"}],"jpcoar:affiliationName":[{"@value":"Northwestern Polytechnical University"}]},{"@id":"https://cir.nii.ac.jp/crid/1380869859565483265","@type":"Researcher","foaf:name":[{"@value":"Xiao Liu"}],"jpcoar:affiliationName":[{"@value":"Harbin Engineering University"}]},{"@id":"https://cir.nii.ac.jp/crid/1380869859565483266","@type":"Researcher","foaf:name":[{"@value":"Bo Zhou"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"1559128X"},{"@type":"EISSN","@value":"21553165"}],"prism:publicationName":[{"@value":"Applied Optics"}],"dc:publisher":[{"@value":"Optica Publishing Group"}],"prism:publicationDate":"2024-01-25","prism:volume":"63","prism:number":"6","prism:startingPage":"A44"},"reviewed":"false","dc:rights":["https://doi.org/10.1364/OA_License_v2#VOR","https://opg.optica.org/policies/opg-tdm-policy.json"],"url":[{"@id":"https://opg.optica.org/viewmedia.cfm?URI=ao-63-6-A44&seq=0"}],"createdAt":"2024-01-09","modifiedAt":"2024-08-06","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360588381067857024","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Investigation of Instantaneous Velocity-Fields by Schlieren Image Velocimetry Using Ray-Traced Simulated Focusing-Schlieren Images"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1364/ao.509665"},{"@type":"CROSSREF","@value":"10.2514/6.2025-0238_references_DOI_965FcCQywpLiTlDgzqcMIU6fpte"}]}
