Demonstration of MIE-Resonance Based Thermal Imaging Optical Window (Case No. 2023-253
This video shows the optic being rotated along a central axis (a polar rotation), and demonstrates that the angular field of view of the optic is high. Specifically, in this video the optic is rotated to an angle of 70 degrees to the axis of the camera, where you can see the image contrast begins to diminish. The optic is then brought closer and this is done a second time to show what the effect would be like if the optic was closer to the camera. This shows it's a good window, if you look through it at a range of angles you can still see to the other side without noticeable contrast deterioration until very high angles, which is what you would expect for its visible counterpart.

Pipeline System Integrity Management - Professor Mosleh; UCLA Case No. 2022-279
UCLA Researchers led by Professor Mosleh have developed an advanced and user-friendly software to address the safety challenges presenting in the pipeline industries. It is a comprehensive assessing tool with a system-level prognosis and health monitoring (PHM) capabilities for PSIM, and it serves as a “one-stop-shop” for the pipeline operators to inspect and analyze the health state of the pipelines and have optimized mitigation suggestions accordingly. Compared to the traditional pipeline integrity management solution, this innovation considers dynamic and time-dependent mitigation actions to the pipeline operators. The information of optimized sensor placement and updated inspection/maintenance schedule is passed back to the predicting model as the field data to constantly optimize the mitigation plans to avoid or reduce the likelihood of pipeline failure at a lower cost. Due to its ease of integration with different types of pipeline systems and versatility of proposed data analytics techniques, this PSIM solution as a whole can be easily adapted with other types of pipeline systems that are used for large-scale infrastructure.

Deep Learning Super-Resolution Magnetic Resonance Imaging via Slice-Profile-Transformation Based Downsampling
Dr. Kyung Sung and his team have developed a novel slice-profile transformation super-resolution (SPTSR) framework with deep generative learning for through-plane super-resolution (SR) of multi-slice 2D MRI imaging. After training their framework with 3,453 clinical subjects, they validated the framework in 392 patients and had two genitourinary radiologists qualitatively evaluate images taken with the framework in 50 patients. They found that this approach overcomes some of the current limitations of conventional approaches and reduces the need for acquiring additional orthogonal imaging planes. This method helps address the physical discrepancies between slice-encoding and frequency/phase-encoding in 2D MRI. Their novel approach is applicable across various disease contexts and results in higher accuracy imaging and reduced MRI acquisition time, making it a valuable tool in clinical settings to increase patient care and reduce the time burden on clinicians.

DeepAdjoint Photonic Structures
Professor Raman and his research team have invented an interactive materials design tool called DeepAdjoint that helps non-experts expedite the design of photonic structures, or electromagnetic components in general. This platform optimizes across materials and geometries simultaneously and supports various classes of NNs such as generative adversarial networks (GANs), variational autoencoders (VAEs), and multilayer perceptrons (MLPs). It seamlessly streamlines advanced ML techniques with improved optimization methods to realize an automated electromagnetic metamaterials design process. An engineer with limited domain knowledge or experience can specify an arbitrary optical design target, and then achieve a photonic structure with the desired optical properties all within a single user-friendly application interface. Additionally, this design tool is generalizable and paves the way towards the systematic unification of ML and optimization algorithms for materials inverse design.

2021-359 Seeing Through Random Diffusers Without a Computer
UCLA researchers led by Professor Aydogan Ozcan have developed an all optics-based system that can perform image reconstruction at the speed of light for images distorted by light scattering and diffusion. By working purely with optics this approach works at the speed of light and does not require digital communication or power. This all-optical approach is an improvement which is orders of magnitude faster than digital approaches and adaptive optics.
