We have developed a new type of computational microscope that uses a compact array of "micro-cameras" to jointly record high-resolution video across large areas. We refer to these novel systems as “multi-camera array microscopes” (MCAMs), which contain up to 96 individual synchronized image sensors and associated lenses to produce gigapixel-scale snapshot measurements.

NASA has awarded 24 postdoctoral fellowships for 2024 in astrophysics, including one to an upcoming PhD graduate of the Wyant College of Optical Sciences, Jaren Ashcraft. As one of eight selected Sagan Fellows, Jaren's proposal title was, "Optimizing the Vector Field for Next-Generation Astrophysics."

Congratulations to all the students taking on exciting roles as SOCk and WiO officers. We cannot wait to see what the upcoming school year holds.

Laser Fun Day 2024 attracted over 400 visitors and was made possible by over 100 volunteers. On the day of the event, the building was filled with hands-on activities and demonstrations that showcased the amazing world of optics. The third floor was especially busy with many visitors coming in from the solar telescope and fresnel lens, set up out front of the building. Once inside, they found many more stations set up on the third floor and extending throughout the rest of the building, including a cow-eye dissection and pickle light bulb in Meinel 307. A special thanks to SPIE and Optica for supporting this event.

This study evaluated the sensitivity of label-free fluorescence lifetime imaging (FLIm) as a novel method for detecting low-grade GI inflammation. FLIm captures changes in the tissue microenvironment altered under inflammatory conditions...These findings hint at the quantifiable detection of inflammatory changes in mucosal tissue using FLIm, providing a foundation for further investigations into its sensitivity to colon epithelial metabolism and its potential for monitoring inflammation in live tissue.

In this talk I will discuss our investigation of the general feasibility of this phenomenon as well as our explorations into several promising engineered scenarios that seek to exploit this opportunity. In addition to our ongoing work, I will introduce a variety of interesting open questions that have emerged during our efforts.
