Bringing Our History to Light – X-ray Imaging of Ancient Materials from Archimedes to Gutenberg

Wednesday, October 16
3:00 - 4:00 PM

The 10th century parchment document known as the Archimedes Palimpsest, contains the oldest surviving copy of works by the Greek genius Archimedes of Syracuse (287 – 212 BC). To uncover his obscured writings, 20 years ago we developed the synchrotron-based technique of rapid-scan X-ray fluorescence (XRF) imaging at the Stanford Synchrotron Radiation Lightsource. Since its successful application in the Archimedes imaging project, we further optimized the method, enabling us to carry out numerous XRF imaging studies of large objects of cultural, archaeological, and paleontological importance. We will describe the X-ray sources and imaging methods and present several examples of our quest to bring to light our cultural and natural heritage with X-rays. We will conclude the lecture with our recent work on disentangling the carbon chemistry of Australian plant exudates from a unique historical collection. These extraordinary plant materials have been used for millennia for various applications and are still employed in contemporary art. To probe deep into the bulk of these materials, we employed a powerful hard X-ray technique that overcomes some of the limitations of conventional carbon X-ray spectroscopy. Please join me in a fascinating journey through our ancient history and see how powerful modern X-ray imaging methods help us to uncover it.

With the advent of a new generation of high-performance astronomical spectrographs, the discovery of “Earth 2.0” is within reach. Yet Doppler searches for earthlike, habitable planets are plagued by parasitic signals from gas motion in stellar atmospheres and false positives produced by observing cadence and data analysis methods. Almost all Doppler planet-search teams use some variant of the periodogram to identify velocity signals caused by planets. Unfortunately, the Lomb-Scargle periodogram for unevenly spaced time series suffers from bias-causing spectral leakage and does not become less noisy as the number of observations increases. I will describe how adapting the Thomson multitaper technique to unevenly sampled, gapped astronomical time series can improve our prospects for planet detection. I will then show how magnitude-squared coherence and phase estimates allow us to diagnose the insidious false positives that come from stellar rotation and magnetism. Finally, I will illustrate two interesting astronomical imaging methods that are useful for exoplanet science - bolometry and angular differential imaging - and discuss the possible use of 2-d Slepian tapers in Fourier analysis of images.

Computational Framework for the Elastography Inverse Problem

 

Basca Jadamba

Basca Jadamba
Professor in the School of Mathematics and Statistics
Associate Head, Applied and Computational Mathematics
Rochester Institute of Technology

Early detection and treatments are key components in improvements in patient survival rates in cases of soft tissue cancers such as breast cancer. In this talk, we will introduce a computational framework for a parameter identification problem involving a system of partial differential equations (PDEs) describing displacements in soft tissues under applied forces where tissue displacements are obtained from imaging systems such as ultrasound. The focus of the work is the recovery of a spatially varying parameter in the model where the underlying mathematical problem is an optimization problem where the system of PDEs serves as a constraint. We introduce an adaptive mesh refinement framework based on finite element methods where the main goal is improved computational efficiency while still providing the resolution needed for accurate recovery of the parameter.

Spectral Imaging for Heritage Science: Workflows for Image Processing and Analysis

Chester F. Carlson Center for Imaging Science

While on sabbatical at the University of Durham, UK, I worked with “Team Pigment,” a multidisciplinary collaboration between the departments of Chemistry, History, and the Institute of Medieval and Early Modern Studies (IMEMS), to build image capture, calibration, and processing workflows for multispectral and hyperspectral imaging of historical artifacts. Our camera systems include spectrally filtered multispectral imagers that are portable for use in a wide range of institutions, as well as Vis-NIR-SWIR hyperspectral imaging systems for use in the Palace Green Library at Durham. While there, we imaged over 100 artifacts, ranging from medieval manuscripts, Shakespeare’s First Folio, Persian art works, and an obscure medieval book binding, all with the goal of learning more about the content, and context, of these artifacts. The workflows will be introduced and examples of tasks such as pigment mapping, ink mapping, faded text enhancement, and underdrawing identification will be shown. Ongoing projects will also be presented.


The World Where Every Photon Counts

Speaker: Sergey Polyakov

Photon counting opens a door into a new world. Quantum effects emerge. Beyond fundamental interest, those effects lead to unprecedented accuracy of measuring light, often surpassing capabilities of classical sensors. Quantum-enabled photonic techniques can enhance nearly every traditional application in optics: from astronomy to biology and from communications to imaging. I will talk about our recent experiments with faint light that enable practical quantum advantage by demonstrating below-the-shot-noise sensitivity and super-resolution. Let me show you a new world that connects fundamental laws of nature with everyday optical technologies.
