Near-Infrared Spectroscopy Probes Food Freshness
Near-infrared (NIR) spectroscopy is well-suited to analysis of bulk, high-moisture agricultural samples such as fruit, grains, fish and meat. Light at NIR wavelengths penetrates samples with less scattering than other techniques, allowing internal composition to be analyzed nondestructively. Although NIR spectra are often broad, overlapping and complex, statistical modeling can be used to unlock their secrets.

Photobiomodulation Therapy Comes of Age
Important advances in our understanding of the basic science of photobiomodulation (PBM) are influencing the development of laser technology and the use of these devices to treat a number of diseases and injuries. PBM is the mechanism by which non-ionizing optical radiation in the visible and NIR spectral range is absorbed by endogenous chromophores to elicit photo-physical and photo-chemical events at various biological scales.

New Treatment for Inflammatory Disease Uses Optogenetic Tool
An optogenetic approach to regulating inflammation and immunity in the human body employs photocontrolled inhibitors that are selectively delivered to the target cells via UV radiation. This novel approach could further the study of inflammation and the immune system, and could ultimately lead to a means to control inflammation in vivo, while minimizing side effects to healthy tissues.

Graphene-Laced Silly Putty Creates Sensors
By infusing silly putty (polysilicone) with graphene, researchers have produced an extremely sensitive sensor they call “G-putty.” They found that when the graphene was added, the silly putty was able to conduct electricity and became very sensitive to deformation and impact.

Large-Scale, Deep-Tissue Neuronal Imaging
Thu, Apr 20, 2017 1:00 PM - 2:00 PM EDT
Lingjie Kong, Ph.D., will speak on advances in large-scale deep tissue imaging of biological dynamics, focusing on applications in neuroscience. Kong received his Ph.D. in Optical Engineering from Tsinghua University in 2012. For postdoctoral training, he worked at X. Sunney Xie's group at Harvard University, Meng Cui's group at Howard Hughes Medical Institute's Janelia Research Campus and Purdue University. He is currently engaged in research work at Purdue University and is planning to join the faculty at Tsinghua University.

Introducing the CAOS Smart Camera - Empowering Extreme Imaging
Wed, Apr 26, 2017 1:00 PM - 2:00 PM EDT
Nabeel A. Riza, Ph.D., chair professor of Electrical and Electronic Engineering at University College Cork, will discuss the development of the Coded Access Optical Sensor (CAOS) and how the CAOS sensor, working in unison with CMOS sensors, can smartly extract scene contrast pixel light intensity information using time-frequency coding of selected agile pixels. He will discuss how CAOS addresses the challenges to reaching extreme all-linear, instantaneous dynamic ranges with multicolor smart capture of targets of interest within extreme contrast images and provide a demonstration of a version of CAOS called the CAOS-CMOS camera. Who should attend: engineers, scientists, researchers and technical professionals who may require or are interested in extreme contrast imaging.
