2:30 to 3:00 PM: Photovoltaics Moving into the Terawatt Age

Eicke R. Weber, Berkeley Education Alliance for Research in Singapore BEARS (Singapore) and Univ. of California, Berkeley (United States)

In the last few years, PV electricity became cost-competitive with electricity produced by conventional sources. Global PV production capacity will double within the next five years to 100-120 GWp/a, bringing PV installations into the Terawatt range. A key factor for this growth will be continuous technology advances aimed at higher efficiencies at reduced cost. In addition, cell efficiency will be even more important than lowest cost, to optimize energy harvest from a given area. Crystalline Silicon technology currently represents 90% of the global PV market. This technology is approaching a ceiling of 29% efficiency for a single-bandgap semiconductor. New approaches for higher efficiencies require heterojunctions, and several approaches will be discussed. These include heterojunctions on silicon, allowing to combine well-established large-scale Silicon PV technology with new technologies, such as low-cost III/V or Perovskite layers.

Professor Eicke R. Weber is Director/CEO of the Berkeley Education Alliance for Research in Singapore (BEARS).

Session Chair: Abdul A. S. Awwal, Lawrence Livermore National Lab. (United States)

1:30 to 2:30 PM: Fast Automated 3D Modeling of Building Interiors


Avideh Zakhor, Univ. of California, Berkeley (United States)

In this talk, I will present a mapping and visualization platform for 3D modeling and documentation of indoor environments. Unlike existing mobile mapping systems with wheels, our proposed hardware acquisition devices are human wearable and hence must compensate for complex human gait. Furthermore, lack of GPS in indoor environments precludes us from applying existing outdoor mapping techniques indoors. We propose two distinct hardware systems to accomplish this task. The first one is an ambulatory backpack system equipped with a suite of sensors worn by an operator walking at normal speeds in and out of rooms inside a building in a continuous walk through. The second one is a handheld system carried by a human operator as s/he waives it at walls while walking inside the building. Both systems share a common software pipeline that results in 3D point clouds, texture mapped surface reconstructed 3D models, 3D architectural models and floor plans, and web based virtual navigation with tagging, annotation, and dimension measurement capability. We also describe a visual analytic platform that can be used to automatically recognize energy relevant assets such as windows, lights, and computers. The same walkthrough that generates 3D model can also be used to collect building sensor fingerprints which can later be used in a mobile app to locate building occupants, for example by first responders in emergency situations. I will describe some of the challenges in design and implementation of this platform and outline a number of open technical problems.

Avideh Zakhor is currently Qualcomm Chair and professor in EECS at U.C. Berkeley. Her areas of interest include theories and applications of signal, image, and video processing and 3D computer vision.

Optical Engineering Plenary Session
Date: Tuesday 8 August 2017
Time: 4:00 PM - 5:30 PM
Session Chair: Julie L. Bentley, Univ. of Rochester (United States)

4:00 to 4:05 PM: Welcome and Opening Remarks

4:05 to 4:45 PM: Designing for One to One-Million: How Production Quantities Influence Design


Leo B. Baldwin, Amazon.com, Inc. (United States)

One of the most significant factors in product design is the production quantity. Along with unit price, it determines what is possible and what is prudent in allocating resources to the engineering, to the tooling, and to the material costs. From the extreme of producing one or two units to the other extreme of producing over a million units, these trade-offs are discussed in the context of optical and photonic systems. These trade-offs are illustrated using examples of products produced for the capital equipment and consumer electronics markets covering the gamut of production quantities with particular attention given to optical components.

Leo Baldwin studied physics at Waterloo and modern optics at Rochester. He has spent his 37 year career designing products. Early products included missile guidance systems, reactor cores and submarines. Leo soon gravitated to photonics, designing high speed cameras, scopes, and a helicopter landing system. Moving from government systems to commercial systems, and moving from Canada to the US, Leo began designing inspection and guidance systems, first for containers and then for electronic and semiconductor capital equipment. This lead to designing laser micro-machining systems and designing nanostructures. Leo moved to consumer electronics, designing a custom pixel, a custom sensor, and custom lenses for cell phones and tablets. Leo is currently designing the vision based infrastructure for a new kind of smart store where you Just Walk Out - no check-out lines! Leo's original design work has resulted in 58 US patents.

4:50 to 5:30 PM: The Large Synoptic Survey Telescope


Steven M. Kahn, Large Synoptic Survey Telescope (United States) and SLAC National Accelerator Lab. (United States)

The Large Synoptic Survey Telescope (LSST) is a large aperture, wide-field, ground-based telescope designed to provide a time domain survey of the entire southern hemisphere in six optical bands. Over the ten-year duration of the survey, LSST will obtain ~800-1,000 images of every part of the southern sky, yielding a catalog of stars, galaxies, and moving small bodies in the solar system with nearly 40 billion objects. A diverse array of scientific investigations can be performed with a common database addressing topics ranging from the detection of potentially hazardous asteroids to the structure and evolution of the Universe as a whole. LSST incorporates an 8-m class primary mirror with a 3.2 billion pixel camera. I will discuss the design of this facility and our technical progress with construction and fabrication of the key components.

Steven M. Kahn is the Cassius Lamb Kirk Professor in the Natural Sciences in the Physics Department at Stanford University, and a Professor of Particle Physics and Astrophysics at SLAC National Accelerator Laboratory. Prior to moving to his present position at Stanford in 2003, Kahn held faculty appointments at Columbia and Berkeley. He is an experimental astrophysicist who has led major programs in X-ray astronomy and experimental cosmology. He is currently the Director of the Large Synoptic Survey Telescope Project. Kahn is a Fellow of the American Physical Society, the American Association for the Advancement of Science, and the American Academy of Arts and Sciences.
Remote Sensing Plenary
Date: Wednesday 9 August 2017
Time: 10:30 AM - 11:20 AM
Session Chair: Allen H.-L. Huang, Univ. of Wisconsin-Madison (United States)

10:30 to 11:20 AM: Demonstrating Technologies for Hyperspectral Infrared Remote Sensing from Space on a CubeSat

Thomas S. Pagano, Jet Propulsion Lab. (United States)

CubeSats offer a low cost platform for remote sensing and in-situ measurements in space. Not only is the cost of the spacecraft low, but also the cost of the launch since typically CubeSats are secondary payloads to the primary satellite being launched. Despite the low available volume, mass and power and a typically less than ideal orbit, the platform can be ideal for demonstrating technology and even achieving certain science quality measurements. In this talk we discuss the CubeSat Infrared Atmospheric Sounder (CIRAS) a new project at NASA JPL designed to demonstrate key technologies for hyperspectral infrared measurements of atmospheric temperature and water vapor from space.

Mr. Thomas S. Pagano is the Project Manager for the AIRS/AMSU/HSB Suite of instruments on the EOS Aqua Spacecraft and the Principal Investigator of the CubeSat Infrared Atmospheric Sounder (CIRAS). He was the lead engineer responsible for the calibration of the AIRS instrument in orbit and the Chief Systems Engineer on the MODIS instrument. He holds 2 US patents and is author of numerous papers on space remote sensing systems.
