Barrel-Eliminating Optical Element Enables Massive Zoom in Tiny Form Factor
Barrel-Eliminating Optical Element Enables Massive Zoom in Tiny Form Factor
A novel optical element will one day enable composite lenses and telescopes in a form factor small enough to fit in a pocket. The device, called a spaceplate, is designed to mimic the empty space needed to focus an image — meaning one day photographers will be able to take pictures of faraway subjects without a long-barrel telephoto lens.

Quantum Microscope Achieves Unprecedented Clarity in Cellular Imaging
Quantum Microscope Achieves Unprecedented Clarity in Cellular Imaging
A quantum microscope developed at the University of Queensland can resolve cellular structures that would otherwise be impossible to see. The designing researchers showed that quantum correlations can increase performance beyond the limit imposed by photodamage in other microscope configurations, in work that overcomes a significant barrier in furthering microscopy for biological imaging.

Fluorescence Microscopy Technique Images Deep Brain in High Resolution
A noninvasive brain imaging technique developed by researchers at ETH Zurich and the University of Zurich works in the near-infrared (NIR) spectrum to enable superresolution deep-tissue fluorescence microscopy at four times the depth limit imposed by light diffusion. The technique, diffuse optical localization imaging (DOLI), operates in a resolution-depth regime previously inaccessible with optical methods.

.: Vision Spectra Conference

 
Is It a Wolf or a Husky? Can You Trust Your AI Vision Model? Presentation: Is It a Wolf or a Husky? Can You Trust Your AI Vision Model?
Presented by: Ted Way, Microsoft

Artificial intelligence is ubiquitous in computer vision applications — from self-driving cars to retail, healthcare, manufacturing, and beyond. How do you know your computer vision AI model is working as advertised?

In his presentation, Ted Way, Ph.D., a program manager lead for the Microsoft Insights Apps AI team, will cover various ways that AI models can be fooled, such as by adding stickers to a stop sign. The session will also focus on using techniques to probe how a vision AI model makes a decision. Finally, Way will show how the LIME (local interpretable model-agnostic explanations) technique explains what an AI model is doing when it's looking at pictures of wolves and huskies, for example.

The inaugural Vision Spectra Conference runs July 20 - 22. Registration is free for the event, which is offered exclusively online. For more information and registration, please visit www.photonics.com/vsc2021. Continued coverage of this inaugural event will also be available on vision-spectra.com and Photonics.com leading up to the conference.
