Quantitative refractive index tomography of millimeter-scale objects using single-pixel wavefront sampling

Professor Chulmin Joo's research team at the Department of Mechanical Engineering introduced an optical diffraction tomography (ODT) method capable of producing 3D refractive index (RI) distribution of transparent samples via a single-pixel detector. Conventional ODT based on optical interferometry can produce high-resolution 3D RI maps, but the interferometry-based ODT is unsuitable for imaging large samples exceeding several tens of micrometers and is greatly influenced by speckle noise. This study presents a noise-robust 3D phase tomography technique suitable for imaging millimeter-scale objects. This research was published in the journal 'Optica' (top 6.93% in Optics, Impact Factor: 10.644) on September 19, 2022.
