Recent VOSA Meeting

Tuesday 9 April
The Basic Science of Climate Change
VOSA 190409
Professor Joern Callies
California Institute of Technology
Abstract:  This presentation looks at the basic mechanisms that cause global warming and other changes in the climate system.  We will discuss Earth's energy balance and radiative transfer, how changes in the atmospheric composition affect it, and what feedbacks are at play in mediating the climate system's response to increasing greenhouse gas concentrations..
Venue:  Advanced Spectral Technology, Inc.

Next OSSC Meeting

Wednesday 8 May

Abstract:  Multi-layer optical coatings play a key part in modern photonics, tailoring optical properties to create high-performance mirrors, low reflectivity surfaces, and wavelength or polarization dependent optics.  Without such coatings, many optical systems would not be practical, or even possible.  While multi-layer optical coating technology has developed tremendously since its inception in the 1940’s, there are still challenges that can lead to failed designs and require optimization by trial and error.
Much of the trial and error in coating design is driven by the difficulty in accurately specifying index dispersion for each material.  While index dispersion can be approximated by bulk index values or thin film measured values, for many this is insufficient to accurately design a coating without multiple iterations.  What is required is an accurate estimate of index dispersion produced by a particular coating technique on a particular machine.
The IDEM system provides a unique index calibration for each material and process used in particular machine.  IDEM then monitors the reflected vis/NIR spectrum (400nm-900nm), fitting the reflectivity curve derived for the layer’s calibrated index dispersion and the combined dispersion of the substrate and previous layers (IDEM can track more than four layers on one witness chip), rather than monitoring a key wavelength.  Additional benefits are continuous insight into system performance, and ability to restart a coating run after a system interruption. IDEM significantly increases the reliability and efficiency of creating multi-layer optical coatings, reducing lead-time and increasing cost margin.

Connecting the Unconnected

Dr. Hamid Hemmati,
Director of Engineering – Telecom Infra
Facebook Research
Abstract:  Nearly half the world population, greater than three billion in total, has either no access or fairly poor access to the Internet.  Facebook, through its partnership intends to provide Internet access to the developing countries of the world.  The required data-rate to provide Internet service in those online simultaneously in these countries is estimated at over 1 Tbps. This is a staggering data-rate.  Cost effective means are required to make the service possible and that requires significant advancements of the state-of-the-art in technology.

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

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.
