High throughput spatially sensitive single-shot quantitative phase microscopy
Azeem Ahmad, Vishesh Dubey, Nikhil Jayakumar +7
High space-bandwidth product with high spatial phase sensitivity is indispensable for a single-shot quantitative phase microscopy (QPM) system. It opens avenue for widespread appli…
Soft thresholding schemes for multiple signal classification algorithm
Sebastian Acuña, Ida S. Opstad, Fred Godtliebsen +2
Multiple signal classification algorithm (MUSICAL) exploits temporal fluctuations in fluorescence intensity to perform super-resolution microscopy by computing the value of a super…
Simulation-supervised deep learning for analysing organelles states and behaviour in living cells
Arif Ahmed Sekh, Ida S. Opstad, Rohit Agarwal +5
In many real-world scientific problems, generating ground truth (GT) for supervised learning is almost impossible. The causes include limitations imposed by scientific instrument,…
Fluorescence fluctuations-based super-resolution microscopy techniques: an experimental comparative study
Ida S. Opstad, Sebastian Acuña, Luís Enrique Villegas Hernandez +4
Fluorescence fluctuations-based super-resolution microscopy (FF-SRM) is an emerging field promising low-cost and live-cell compatible imaging beyond the resolution of conventional…
On-chip TIRF nanoscopy by applying Haar wavelet kernel analysis on intensity fluctuations induced by chip illumination
Nikhil Jayakumar, Øystein I Helle, Krishna Agarwal +1
Photonic-chip based TIRF illumination has been used to demonstrate several on-chip optical nanoscopy methods. The sample is illuminated by the evanescent field generated by the ele…
Multi-modal on-chip nanoscopy and quantitative phase image reveals the morphology of liver sinusoidal enodthelial cells
David A. Coucheron, Ankit Butola, Karolina Szafranska +6
Visualization of three-dimensional morphological changes in the subcellular structures of a biological specimen is one of the greatest challenges in life science. Despite conspicuo…
High space-bandwidth in quantitative phase imaging using partially spatially coherent optical coherence microscopy and deep neural network
Ankit Butola, Sheetal Raosaheb Kanade, Sunil Bhatt +7
Quantitative phase microscopy (QPM) is a label-free technique that enables to monitor morphological changes at subcellular level. The performance of the QPM system in terms of spat…
A transparent waveguide chip for versatile TIRF-based microscopy and nanoscopy
Anish Priyadarshi, Firehun Tsige Dullo, Deanna L. Wolfson +6
Total internal reflection fluorescence microscopy (TIRF) has enabled low-background, live-cell friendly imaging of cell surfaces and other thin samples thanks to the shallow penetr…
High spatially sensitive quantitative phase imaging assisted with deep neural network for classification of human spermatozoa under stressed condition
Ankit Butola, Daria Popova, Dilip K Prasad +8
Sperm cell motility and morphology observed under the bright field microscopy are the only criteria for selecting particular sperm cell during Intracytoplasmic Sperm Injection (ICS…
