DESCRIPTION:Speakers: Yaping Zhang (Kunming University of Science and Tech
 nology and Cambridge University)\, Ting-Chung Poon (Virginia Tech)\n\nDigi
 tal Holography for Recording and Reconstructing 3D Information \nDigital 
 holography (DH) offers a unique approach to recording and reconstructing t
 hree-dimensional (3D) optical information. Unlike conventional imaging met
 hods\, DH records both the amplitude and phase of light\, allowing fine st
 ructural details and depth information to be preserved and numerically rec
 onstructed. These capabilities make DH valuable not only for 3D imaging an
 d optical metrology\, but also for cultural heritage preservation\, digita
 l archiving\, biomedical imaging\, and other interdisciplinary application
 s. Because holographic techniques are non‑contact and non‑destructive\
 , they are well suited for recording delicate surface structures and detec
 ting extremely small deformations.\nThis talk will introduce the basic pri
 nciples of holography and digital holography\, followed by several example
 s of holographic recording and reconstruction. Current challenges\, includ
 ing computational complexity\, data volume\, and limitations in holographi
 c display\, will also be discussed. The talk will conclude with a brief ex
 ploration of what digital holography could offer to digital humanities and
  related fields in the future.\n \n \nOptical Scanning Holography (OSH):
  A Single‑Pixel Approach to Real‑Time Digital Holographic Recording\n
   I will introduce optical scanning holography (OSH)\, a single‑pixel\,
  real‑time digital holographic recording technique. The talk will conclu
 de by highlighting a diverse range of current and emerging OSH application
 s\, from fluorescence and phase‑contrast microscopy to the acquisition o
 f small 3D sculpture holograms. I will also consider prospective intersect
 ions with the digital humanities\, particularly for the preservation and v
 isualization of cultural heritage\, including paintings and murals\, witho
 ut the stitching requirements characteristic of conventional digital holog
 raphy.\n \nVideoconference via https://us02web.zoom.us/j/87583276781\n \
