Researchers Deploy Metasurface Tech to Design Encryption Devices
Researchers from the University of St. Andrews in Scotland developed a metasurface-based device that produces multiple distinct holographic images depending on the surrounding medium and the wavelength of light used. The ability to store information that is only retrievable with the right set of keys — such as a certain light wavelength combined with wet conditions — could be further developed to design simple yet effective encryption devices.

Laser Endomicroscopy Enables Lung Cancer Detection in Real Time
Researchers at the Abramson Cancer Center at the University of Pennsylvania have developed a method to detect lung cancer at the cellular level in real time during biopsy. The method ensures earlier detection of cancer cells that may have been too small to detect using existing technology.

Advances in LED Illumination for Fluorescence Imaging
Thu, Jun 2, 2022 10:00 AM - 11:00 AM EDT
LED illumination for fluorescence microscopy systems has progressed significantly. Kavita Aswani Ph.D. describes the latest advances in illumination for fluorescence imaging, from near-UV to NIR fluorophores. LED illumination systems are successfully replacing traditional arc lamps in calcium imaging applications and producing equivalent results with the convenience of LEDs. IR versions of the light sources allow imaging of the popular ICG (indocyanine green) and IR800 dyes. They provide high signal to-noise ratios because of the low background in the NIR region. NIR wavelengths also allow for greater depth penetration in thicker tissues and living animals. Presented by Excelitas Technologies Corp.

Laser Measurement Solutions for Materials Microprocessing Applications
Wed, Jun 15, 2022 11:00 AM - 12:00 PM EDT
Mark Slutzki, a product manager at Ophir, shares innovative solutions for the challenges that accompany materials microprocessing applications. Those who use lasers in these applications, such as drilling via holes in PCBs, organic LED display lift-off, and cutting smartphone cover glass, are faced with many challenges. While the combination of laser parameters enables new and innovative processes, they can also cause unexpected damage to the measurement tools used to keep the process stable. These parameters include ultra-short pulse duration, high repetition rates, short wavelengths, and many others. Sponsored by Ophir, LaserPoint srl, and DataRay Inc.

.: All Things Photonics

Nobel laureate Donna Strickland joins Francois Légaré and Heide Ibrahim from the Advanced Laser Light Source Laboratory (ALLS), located outside Montreal. The panel discusses the specifications of the ALLS laser systems, their functionality, and their applications in molecular imaging, agriculture, and metrology. Jan Lagerwall, head of the Experimental Soft Matter Physics group at the University of Luxembourg, introduces nonconventional applications for liquid crystals, including in sensing, machine vision, and more.
