Structured Random Models for Phase Retrieval with Optical Diffusers
Zhiyuan Hu, Fakhriyya Mammadova, Julián Tachella +2
Phase retrieval is a nonlinear inverse problem that arises in a wide range of imaging modalities, from electron microscopy to Fourier ptychography. In particular, the reconstructio…
A global inverse-problem approach to quantitative photo-switching optoacoustic mesoscopy
Yan Liu, Jonathan Chuah, Michael Unser +1
In this paper, we propose a global framework that includes a detailed model of the photo-switching and acoustic processes for photo-switching optoacoustic mesoscopy, based on the u…
Revisiting PSF models: unifying framework and high-performance implementation
Yan Liu, Vasiliki Stergiopoulou, Jonathan Chuah +5
Localization microscopy often relies on detailed models of point spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation…
Perturbative Fourier Ptychographic Microscopy for Fast Quantitative Phase Imaging
Martin Zach, Kuan-Chen Shen, Ruiming Cao +3
In computational phase imaging with a microscope equipped with an array of light emitting diodes as illumination unit, conventional Fourier ptychographic microscopy achieves high r…
Point-Spread-Function Engineering in MINFLUX: Optimality of Donut and Half-Moon Excitation Patterns
Yan Liu, Jonathan Dong, Juan Augusto Maya +2
Localization microscopy enables imaging with resolutions that surpass the conventional optical diffraction limit. Notably, the MINFLUX method achieves super-resolution by shaping t…
Structured Random Model for Fast and Robust Phase Retrieval
Zhiyuan Hu, Julián Tachella, Michael Unser +1
Phase retrieval, a nonlinear problem prevalent in imaging applications, has been extensively studied using random models, some of which with i.i.d. sensing matrix components. While…
Model-based temporal unmixing towards quantitative photo-switching optoacoustic tomography
Yan Liu, Jonathan Chuah, Yishu Huang +3
Optoacoustic (OA) imaging combined with reversibly photoswitchable proteins has emerged as a promising technology for the high-sensitivity and multiplexed imaging of cells in live…
Mechanical Artifacts in Optical Projection Tomography: Classification and Automatic Calibration
Yan Liu, Jonathan Dong, Thanh-an Pham +2
Optical projection tomography (OPT) is a powerful tool for biomedical studies. It achieves 3D visualization of mesoscopic biological samples with high spatial resolution using conv…
