Specifically, the availability of advanced at-wavelength characterization tools and methods is critical to developing and fabricating the high-quality focusing optics required to achieve diffraction-limited focusing in many instruments deployed at modern X-ray light sources. The multi-contrast imaging methods are also actively investigated for both wavefront sensing and X-ray imaging of bio-samples, including absorption, quantitative phase, and dark-field information. This presentation reports on the latest developments of the advanced algorithms of wavefront sensing and multi-contrast imaging methods at the Advanced Photon Source, including wavelet-transform-based speckle tracking (WXST), optimization-based coded-mask-based multi-contrast imaging (CMMI) method, and AI-accelerated real-time X-ray phase-contrast imaging method (Speckle-based Phase-contrast Imaging Neural Network, SPINNet). As a result of enhancements to both the hardware and software elements, these methods exhibit extraordinary performance in terms of computational efficiency, sensitivity, and resolution. In addition, the wavefront sensing and multi-contrast imaging method based on deep learning, SPINNet, has shown real-time measurement ability with superior quality compared with conventional methods, which promises applications in real-time beamline diagnostics and in-situ imaging of biomedical samples and battery materials both in 2D and 3D.<\/p>\n<p><em>Please note that the meeting URL for this event can be seen on the <\/em>cels-seminars website<em>, which requires an Argonne login.<\/em><\/p>","excerpt":"","slug":"lans-seminar-49","image":false,"all_day":false,"start_date":"2022-08-10 10:30:00","start_date_details":{"year":"2022","month":"08","day":"10","hour":"10","minutes":"30","seconds":"00"},"end_date":"2022-08-10 11:30:00","end_date_details":{"year":"2022","month":"08","day":"10","hour":"11","minutes":"30","seconds":"00"},"utc_start_date":"2022-08-10 15:30:00","utc_start_date_details":{"year":"2022","month":"08","day":"10","hour":"15","minutes":"30","seconds":"00"},"utc_end_date":"2022-08-10 16:30:00","utc_end_date_details":{"year":"2022","month":"08","day":"10","hour":"16","minutes":"30","seconds":"00"},"timezone":"America\/Chicago","timezone_abbr":"CDT","cost":"","cost_details":{"currency_symbol":"","currency_code":"","currency_position":"prefix","values":[]},"website":"","show_map":false,"show_map_link":true,"hide_from_listings":false,"sticky":false,"featured":false,"categories":[{"name":"Seminar","slug":"seminar","term_group":0,"term_taxonomy_id":2,"taxonomy":"tribe_events_cat","description":"","parent":0,"count":761,"filter":"raw","id":2,"urls":{"self":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/tribe\/events\/v1\/categories\/2","collection":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/tribe\/events\/v1\/categories"}}],"tags":[],"venue":{"id":3062,"author":"43","status":"publish","date":"2022-05-02 11:24:10","date_utc":"2022-05-02 16:24:10","modified":"2022-05-02 11:24:10","modified_utc":"2022-05-02 16:24:10","url":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/venue\/https-wordpress-cels-anl-gov-cels-seminars-event-lans-seminar-63\/","venue":"https:\/\/wordpress.cels.anl.gov\/cels-seminars\/event\/lans-seminar-63\/","slug":"https-wordpress-cels-anl-gov-cels-seminars-event-lans-seminar-63","json_ld":{"@type":"Place","name":"https:\/\/wordpress.cels.anl.gov\/cels-seminars\/event\/lans-seminar-63\/","description":"","url":"","address":{"@type":"PostalAddress"},"telephone":"","sameAs":""},"show_map":true,"show_map_link":true,"global_id":"wordpress.cels.anl.gov\/lans-seminars?id=3062","global_id_lineage":["wordpress.cels.anl.gov\/lans-seminars?id=3062"]},"organizer":[],"custom_fields":[],"json_ld":{"@context":"http:\/\/schema.org","@type":"Event","name":"LANS Seminar","description":"&lt;p&gt;Seminar Title: Advanced Algorithms of X-ray Wavefront Sensing and Multi-contrast Imaging Methods for Synchrotron Facilities Speaker: Zhi Qiao, Postdoctoral Appointee, ANL\/AUP Date\/Time: August 10, 2022 \/ 10:30 AM - 11:30 AM Location: See meeting URL on the cels-seminars website\u00a0(requires Argonne &hellip; &lt;a href=&quot;https:\/\/wordpress.cels.anl.gov\/lans-seminars\/event\/lans-seminar-49\/&quot;&gt;Continue reading &lt;span class=&quot;meta-nav&quot;&gt;&rarr;&lt;\/span&gt;&lt;\/a&gt;&lt;\/p&gt;\\n","url":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/event\/lans-seminar-49\/","eventAttendanceMode":"https:\/\/schema.org\/OfflineEventAttendanceMode","eventStatus":"https:\/\/schema.org\/EventScheduled","startDate":"2022-08-10T10:30:00-05:00","endDate":"2022-08-10T11:30:00-05:00","location":{"@type":"Place","name":"https:\/\/wordpress.cels.anl.gov\/cels-seminars\/event\/lans-seminar-63\/","description":"","url":"","address":{"@type":"PostalAddress"},"telephone":"","sameAs":""},"performer":"Organization"}}
