Coherent laser detection and ranging is applied to capture 3D images of objects placed in or behind large fires. A ranging precision of 300 μm through natural
We propose a method for continuously compensating for the polarization state change of photons propagating in fibers. This technique operates at a single-photon

We show sub-200 ps synchronization between quantum networks nodes that are separated by two 64 km deployed fiber links, providing a 128 km link architecture
We experimentally investigate using backward-wave spontaneous parametric downconversion for frequency translation, where spectral characteristics of the pump
Cyber-Physical Systems (CPS) require seamless integration of physical and computation components through communication networks. They often contain sub-systems

We are beginning projects to validate the physics models used for interpretation of electron microscopy images. In one, we will measure electron yields and
Background: Patterning defect metrology requires data interpretation with classification, each well-suited to machine learning (ML). Defect classification
Global population growth and increasing resource scarcity are necessitating sustainable manufacturing and circular economy (CE) practices. These practices
Orienting an entire organization toward sound security practices is an important, but non-trivial undertaking. A starting point for many organizations is to
