UCLA’s Breakthrough in Non-Invasive Imaging: Multispectral QPI Employs Deep Learning for Advanced Scientific Research

As Seen On

Quantitative Phase Imaging (QPI) has long been recognized as a pivotal technique in the realms of scientific and microbiological research, offering an insightful glimpse into the multifarious complexities of the microscopic universe. Its ingrained significance has only been further amplified by the advent of a revolutionary development – Multispectral Quantitative Phase Imaging (QPI).

At the heart of QPI’s functionality lies the creation of optical path length differences for light maneuvering through various materials. The crux of the technique utilizes differences in refractive index distribution and changes in thickness to generate detailed phase images without the need for staining or labeling, a process known in the industry as “non-invasive imaging”.

This powerful tool, QPI, has contributed significantly to numerous fields, encompassing cell biology, pathology, biophysics, materials science, and surface science. Its prowess extends to the exploration of subcellular structures, monitoring cell growth, detection of cancer and pathogens, measurement of thin film thickness, evaluation of optical quality, and analysis of surface roughness, to name a few.

In a groundbreaking development, researchers from the globally acclaimed University of California, Los Angeles (UCLA) have unveiled an innovative design for multispectral QPI. Harnessing the power of Deep Learning, a sector of artificial intelligence that mimics the workings of the human brain, they have created a broadband diffractive optical network. This sophisticated network relies on spatially structured dielectric diffractive layers, optimized meticulously through Deep Learning.

This all-optical phase-to-intensity transformer is another jewel in the QPI crown, routing multispectral QPI signals to predetermined spatial positions and extracting a detailed phase profile. The network smartly transforms and optimizes the multispectral phase information of the input objects, ensuring precise image acquisition and analysis.

In bridging the chasms between advanced technology and scientific research, this ground-breaking contribution from UCLA is reshaping the course of non-invasive imaging. This innovation not only equips the imaging domain with advanced capabilities but also holds a profound potential impact for the broader scientific community. The combined force of multispectral QPI and Deep Learning promises to delve deeper into the microcosm, unmasking newer truths and creating a broader understanding of our world at the microscopic level.

The evolutionary stride taken by UCLA, merging the potent power of QPI, Multispectral QPI, and Deep Learning, marks a significant milestone, promising a future where non-invasive imaging becomes a standard tool equipped with unprecedented analytical prowess.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
