OSC Colloquium: Douglas Shepherd, "Scalable, high-speed, 3D imaging of molecular biology in action" Oct. 14, 2021 Douglas Shepherd I will discuss our recent efforts to reduce uncertainty in quantitative molecular imaging through improvements to the optical methods and computational tools used for high-speed, high-resolution, multiplexed, and volumetric fluorescence molecular imaging. Our efforts include a high numerical aperture oblique plane microscopy framework for 3D spatial transcriptomics in human tissue and a digital micromirror-based structured illumination microscopy framework for live-cell, sub-diffraction limited imaging. Read more OSC Colloquium: Matthieu Bloch, "Towards Covert and Secret Quantum Networks" Oct. 14, 2021 Matthieu Bloch We will discuss the possibility of deploying quantum key distribution that are also covert, in the sense of being provably undetectable by an adversary. While covert key generation over quantum channels is not possible under the same assumptions than QKD, we will show that, perhaps surprisingly, covert secret key generation is possible under mild assumptions regarding the quantum channels. Read more OSC Colloquium: Ron Driggers, "Advanced Infrared Systems" Sept. 23, 2021 Ron Driggers Dr. Driggers will present several topics related to advanced infrared imaging systems. He will start with a general discussion about dual band infrared systems (third generation FLIR). Also included are small pitch, high density focal plane systems that eliminate the need for switched optics. Other topics are strap-down pilotage, full spectrum target acquisition, high energy laser target acquisition, drone sensors and drone detection, and advanced uncooled infrared sensors. Read more OSC Colloquium: David Brady, "Neural Processing and Snapshot Compressive Imaging" Sept. 22, 2021 David Brady This talk reviews diverse compressive tomographic imaging systems and explains evolving sampling system and algorithm designs for such systems. Read more OSC Colloquium: Brandon Chalifoux, "Fabrication, Alignment and Testing of Ultralight Mirrors..." Sept. 8, 2021 Brandon Chalifoux I will present an optical design form for diffraction-limited X-ray telescopes that could in principle enable micro-arcsecond angular resolution without deployable optics, albeit with a detector flying in formation. I will enumerate the opto-mechanical tolerances that would be required for such an optical assembly, and our research activities to address key challenges with mirror figuring, alignment, and testing of these thin acylindrical optical surfaces. I will present recent experimental results from our lab that demonstrate two techniques critical to this effort.
