Motion-guided sparse correction enables expert-quality point tracking across diverse microscopy regimes
Leonidas Zimianitis, Pasindu Thenahandi, Kai Buckhalter +10
Tracking the dynamics of non-canonical biological systems in microscopy videos remains a persistent challenge. Both classical and learning-based trackers depend on expert-reviewed…
High-Sensitivity, High-Throughput Double Sagnac Lateral Shearing Quantitative Phase Microscopy and Tomography with Pseudo-Thermal Illumination
Pawel Goclowski, Maciej Trusiak, Balpreet S. Ahluwalia +1
Quantitative phase microscopy (QPM) enables label-free measurement of local optical path length variations, providing critical insight into the structure and dynamics of transparen…
Lateral shearing optical diffraction tomography of brain organoid with reduced spatial coherence
Pawel Goclowski, Julianna Winnik, Vishesh Dubey +6
Optical diffraction tomography (ODT) is a powerful technique for quantitative, label-free reconstruction of the three-dimensional refractive index (RI) distribution of biological s…
High-Fidelity Single-Shot Quantitative Differential Phase Microscopy Using Pseudothermal Sagnac Interferometer
Pawel Goclowski, Hong Mao, Maciek Trusiak +2
In this letter, a high-fidelity single-shot differential quantitative phase microscopy (dQPM) method is presented to effectively image nearly transparent biological samples. The pr…
Differentiable Microscopy Designs an All Optical Phase Retrieval Microscope
Kithmini Herath, Hasindu Kariyawasam, Ramith Hettiarachchi +7
Designing new optical systems from the ground up for microscopy imaging tasks such as phase retrieval, requires substantial scientific expertise and creativity. To augment the trad…
Piezoelectric MEMS Phase Modulator for Silicon Nitride Platform in the Visible Spectrum
Firehun T. Dullo, Paul C. Thrane, Nikhil Jayakumar +4
Active photonic integrated circuits (PICs) in the visible spectrum are essential for on-chip applications, requiring low-loss waveguides with broad transparency and efficient, low-…
