12 - 14 April
STEAM Career Leadership Conference:
3 Day Leadership Conference for
High School CTE Students
Thanks to all industry supporters who joined our conference in connecting students with their future careers. Exhibitors brought demonstrations, and hands on activities for students throughout the event. The program provided students with industry demonstrations and exhibits, college connections, and non-profit volunteer opportunities to use their skills and build a resume.

The Basic Science of Climate Change
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.

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.

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 Internet.org 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.

The Micro Camera Array Microscope —
Enabling gigapixel imaging for behavioral biology
Dr. Mark Harfouche, CEO & Co-Founder,
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.
