Photoacoustic System Enables Real-Time Neurovascular Imaging
A photoacoustic imaging tool accommodates the need for speed and comprehensive detail in neurovascular imaging. The imaging modality enables an approach to visualize whole-brain hemodynamics and oxygenation in real time. It also tracks fast pathophysiological activities at the micro-vessel level. The approach breaks speed and resolution barriers in brain imaging technologies, and could lead to insights into stroke, dementia, and acute brain injury.

$Diffractive Optical Network Supports Quantitative Phase Imaging$

Diffractive Optical Network Supports Quantitative Phase Imaging
A team of researchers led by Aydogan Ozcan from the Electrical and Computer Engineering Department and California Nanosystems Institute at UCLA has developed a diffractive optical network to replace digital image reconstruction algorithms used in quantitative phase imaging (QPI) systems. The technology uses a series of passive optical surfaces that were spatially engineered with deep learning.

Measuring Long-Wavelength Lasers with IR Cameras, Pyroelectric Scanning-Slit Sensors, and Wavelength Conversion Apparatus
Tue, Jun 7, 2022 1:00 PM - 2:00 PM EDT
Numerous products and techniques have been developed to enable measurement of the beam quality parameters for long wavelength light sources. Kevin Kirkham, senior manager of new business development for Ophir at MKS Instruments, presents on the types of measurement tools available for long wavelength sources and helps determine which tools are appropriate for different applications. While there are many considerations that can significantly impact the laser process, an understanding of performance qualities can ensure users see successful outcomes. Presented by Ophir.

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.
