OSSC
The Optical Society of Southern California was founded in 1951 to increase and disseminate the knowledge of optics and closely allied sciences and to promote the mutual interests of investigators, organizations, teachers and students in these fields. The Society is a local section of the The Optical Society (OSA) and typically meets on the second Wednesday of each month from October through June.  Most of our meetings are open to the public.  Those interested in promoting our goals are encouraged to apply for either Individual or Corporate Membership.

Recent VOSA Meeting

Tuesday 12 February
Transmission Imaging in an SEM:
New Detection Schemes for Improved Qualitative and Rigorous Quantitative Analysis
VOSA 190212 Meeting
by
Jason Holm,
NIST
Jason Holm
Abstract:  Scanning electron microscopes (SEMs) are ubiquitous in materials analysis labs and serve many characterization needs.  The focused electron probe can provide useful information about diverse samples, and detectors designed to collect many signals are commercially available and sufficiently well-developed that non-specialists can obtain meaningful information.  One underutilized signal in the SEM, however, is electrons transmitted through the sample.  Although advances have recently been made to better utilize this signal, most commercially available detectors for transmission imaging in an SEM are limited to basic bright-field and dark-field imaging modes with a few options for annular signal discrimination.
    This talk will briefly show how, for only a few dollars, almost any of the currently available SEM transmission detectors can be modified to provide meaningful and rigorous quantitative information using a small collection of simple physical masks. Different ways to fabricate and implement the masks will be described, and examples of how to obtain useful contrast modes and quantitative results will be provided.
    A new programmable transmission detector that enables both imaging and diffraction in one detector will be described.  A mirror array serves as an electronically reconfigurable objective aperture that can take on any user-defined pattern on the fly.  The mirrors can be programmed to select any part of the transmitted electron signal and direct it to either the digital camera, or to the photomultiplier tube to collect a real-space image.  This way, almost any conventional transmission imaging mode can be implemented in an SEM, and new imaging modes can also be easily explored.  Detector operation is demonstrated with diverse samples including thin foils, nanoparticles, and 2D materials.

Upcoming OSSC Meeting

Wednesday 13 March
The Micro Camera Array Microscope —
Enabling gigapixel imaging
for behavioral biology


by
Dr. Mark Harfouche, CEO & Co-Founder,
Ramona Optics
2019 March OSSC Speaker
Abstract:  High-throughput optical microscopy is currently transforming the research fields of genetics, drug discovery and neuroscience.  Due to challenges with large lens design, no standard microscope can capture more than 50 megapixels per image snapshot, which makes it impossible to simultaneously image at cellular-resolution over a multi-centimeter viewing area (field of view, FOV).  To enable cellular resolution imaging over fields of view 10s of cm in diameter, we utilize an array of miniaturized cameras, tiled in a 12x8 configuration collectively called the MCAM.  Each camera is individually addressable and controllable to enable rapid acquisition over the fields of view as large as 20cm in diameter providing gigapixel scale images.  Preliminary applications for the MCAM are being developed for behavior imaging of zebrafish larvae in collaboration with collaborators at Duke University and Harvard University.

"Advancing Microresonator-Based Photonics Technology at OEWaves"

Andrey Matsko
Abstract:  Crystalline whispering gallery mode resonators (WGMRs) are characterized with kHz optical bandwidths achievable at room temperature.  Such a narrow bandwidth enables their applications for generation of high spectral purity signals in both optical and radio frequency spectral domains.  For instance, WGMR-based self-injection-locked semiconductor lasers can be created in visible and IR and have characteristics better than any other laser of similar size.  As the result, miniature gyroscopes and clocks become feasible. WGMR-based X-Ka band microwave photonic oscillators are characterized with spectral purity unachievable in both optical and electronic devices of similar form factor.  Kerr frequency combs generated in WGMRs pumped with continuous wave light result in generation of femtosecond optical pulses on a chip.  The frequency comb integrated with a miniature agile laser can be utilized for optical frequency synthesis.  These and other applications will be discussed and analyzed in the presentation.
