Title

Deep Learning-Enabled Computational Microscopy and Diffractive Imaging

Abstract

In this presentation, I will provide an overview of our recent work on using deep neural networks in advancing computational microscopy and sensing systems, also covering their biomedical applications, including virtual staining of label-free tissue for pathology. I will also discuss diffractive optical networks designed by deep learning to all-optically implement various complex functions as the input light diffracts through spatially-engineered surfaces. These diffractive processors designed by deep learning have various applications, e.g., all-optical image analysis, feature detection, object classification, computational imaging and seeing through diffusers, also enabling task-specific camera designs and new optical components such as spatial, spectral and temporal beam shaping and spatially-controlled wavelength division multiplexing. These deep learning-designed diffractive systems can broadly impact (1) all-optical statistical inference engines, (2) computational camera and microscope designs and (3) inverse design of optical systems that are task-specific. In this talk, I will give examples of each group, enabling transformative capabilities for various applications of interest in e.g., autonomous systems, defense/security, telecommunications as well as biomedical imaging and sensing.

Donna Strickland Colloquium
OSC Colloquium: Donna Strickland, "High Intensity Fiber lasers for Nonlinear Optics"
3:30 – 5 p.m., Dec. 5, 2024

Ti:sapphire lasers offer the largest bandwidths and therefore the shortest pulses.   The highest laser intensities have been achieved using Chirped Pulse Amplification (CPA) of large diameter solid state lasers.  CPA was needed to avoid damage from the nonlinear process of self-focusing.  The disadvantage of solid-state lasers is the limited average power.  On the other hand, diode pumped fiber laser systems offer significantly higher average power than solid state lasers. Self-focusing is eliminated in single mode fibers by guiding and so nonlinear optics can be beneficial rather than detrimental and used to broaden the gain bandwidth.  Single fiber laser amplifiers will not reach the highest intensities offered by solid state lasers, but in this talk, I will discuss developing fiber laser amplifiers for nonlinear optical interactions such as mid-infrared generation and laser acceleration of electrons that require high intensity and benefit from high average power.

Past Speakers

Hendra Nurdin
3:30 – 5 p.m., Nov. 21, 2024

OSC Colloquium: Hendra Nurdin, "Physical Learning Machines: Classical and Quantum Reservoir Computers and Beyond"

This colloquium will give a brief introduction to reservoir computing, an overview of its theoretical foundations, including the notion of a universal family of reservoir computers that is capable of approximating a certain family of nonlinear maps from input sequences to output sequences, as well as its inherent limitations. It will then motivate and touch on efforts by the speaker and his collaborators to exploit noisy near-term quantum computers as quantum reservoir computers. Finally, the colloquium will conclude with a discussion of research directions for further development of quantum reservoir computers as well as research trends in the broader recent efforts on engineered physical learning machines going beyond reservoir computers.
caleb baker colloquium
3:30 – 5 p.m., Nov. 7, 2024

OSC Colloquium: Caleb Baker, "Doing it for the 'Graph (Design, Function, and System Test Results of the Roman Coronagraph Instrument)"

As the Nancy Grace Roman Space Telescope approaches its planned launch date in 2027, the engineers of one of its two instruments have recent cause to celebrate. Roman’s Coronagraph Instrument (CGI), a technology demonstration chasing direct images of Jupiter-like exoplanets, completed its system-level thermal vacuum test in May 2024, successfully demonstrating that it performs to its threshold requirements in a flight-like environment. Please join me as we walk through the design, function, and performance demonstration of one of the most complex optical instruments NASA has ever attempted to fly.
