Professor Wax goes to China

Dr. Adam Wax traveled to China in May to deliver an invited talk at the 138th Optoelectronics Forum.  Speaking at the Wuhan National Laboratory for Optoelectronics (WNLO) to an audience of faculty and students from the WNLO, the Chinese Academy of Sciences, Wuhan University, and the Wuhan University of Technology, Dr. Wax presented the BIOS lab’s work on phase imaging of mechanical properties of living cells.

In appreciation for his presentation, Dr. Wax was given the Wuhan Optoelectronics Forum commemorative plaque.

Low-cost OCT paper is #1 download

A new paper by Sanghoon Kim and co-authors from the BIOS Lab was the top-ranked download from the journal Biomedical Optics Express in February 2018.  The article, titled "Design and implementation of a low-cost, portable OCT system," describes how a fully functional spectral domain OCT system can be constructed for $7,200 in parts, far less expensive than pre-existing commercial OCT systems.

BOE top downloads, February 2018

In March, the paper continued to attract widespread interest, remaining among the journal's top downloads in the #2 position.

Speckle reduction paper is a top 10 download in January

Another work first-authored by Yang Zhao has been designated a Top Download.  In the month of January 2018, his paper was the 9th most downloaded article from the journal Biomedical Optics Express.  Entitled "Real-time speckle reduction in optical coherence tomography using the dual window method," this article describes a method to reduce speckle noise in OCT images using a single shot, and without requiring any hardware changes.

Dual-axis OCT paper is journal's #3 "Top Download"

A recent paper by Yang Zhao and other members of the BIOS Lab has garnered a Top Download distinction.  Their paper, "Dual-axis optical coherence tomography for deep tissue imaging," which appeared in Optics Letters' 12th issue of 2017, was the journal's third most downloaded article during the month of June.

The article demonstrates that a new dual-axis OCT configuration is capable of imaging much deeper under skin than conventional OCT, and at much higher speeds than previous implementations of dual-axis OCT.

Congratulations to Yang for capturing the attention of the optics community!

Quantitative phase imaging of cell disorder receives media attention

One of our lab's recent research papers has caught the notice of the press.  An article in New Atlas highlights the findings of a Biophysical Journal paper, published by Ph.D. student Will Eldridge and Professor Wax along with co-authors Zach Steelman and Brianna Loomis.  This work describes how the stiffness of cells, which is a key metric in the study of cell function, can be measured in a novel way: by sensing the level of disorder within the cell using Quantitative Phase Microscopy.
