Optics and Photonics for Sensing the Environment

Optics and Photonics in Environment and Pollution Monitoring

  • Stand-off and remote sensing techniques to measure trace gases, particulates and aerosols (including LIDAR, DOAS and FTIR)
  • Novel laboratory techniques and methodologies towards disruptive sensing technology (e.g. frequency combs, photonic sensors on a chip, sensing networks and the Internet of things)
  • Satellite and aircraft-based monitoring (e.g. regional air quality, global warming, global carbon cycle, and carbon sources and sinks)
  • Optics and photonics for improved air and water quality, including transformative optical low-cost sensors

Optics and Photonics in Industrial Environments

  • Optics and photonics for renewable (wind, solar and biofuel) and petrogenic (fossil fuel) energies
  • Novel techniques for monitoring fugitive emissions (fossil fuels, nature gas, mining and nuclear power)
  • Imaging and monitoring of crops for increased efficiency and sustainability in agriculture
  • Optics and photonics for extreme environments, including combustion, propulsion and high-temperature flow (e.g. flames, explosions, plasmas and projectiles)

Melba Crawford

Purdue University, USA

Multi-modality Remote Sensing Data Acquisition and Analysis for High Throughput Phenotyping

Sensing technologies ranging from RGB cameras to hyperspectral imaging and LiDAR are rapidly gaining popularity for field-based high throughput phenotyping applications on airborne and ground-based platforms.  In addition to direct measurements of traditional phenotypes such as height, these sensors potentially provide surrogate measurements for plant structural characteristics (e.g. leaf count and leaf area index) and chemistry (e.g. photosynthesis, and plant stress). Opportunities and challenges associated with acquisition, processing, and analysis of high resolution RGB, VNIR/SWIR hyperspectral data, and discrete return LiDAR data acquired from UAVs for plant breeding experiments focused on advancing sorghum varieties for biofuels will be outlined.  Results from multi-modality, multi-temporal predictive modeling of complex phenotypes such as biomass using data driven machine learning and biophysical models will also be presented in the context of feature extraction and learning with limited training data.  Opportunities to exploit transfer learning across scales will also be discussed.

About the Speaker

Dr. Melba Crawford holds the Chair of Excellence in Earth Observation at Purdue University, where she is the Associate Dean of Engineering for Research and a professor in the Schools of Civil Engineering and Electrical and Computer Engineering, and the Department of Agronomy.  Her research interests focus on development of methods for signal and image processing, and applications of these algorithms to remote sensing problems in defense, agriculture, and natural resource management.  She is currently co-leading a joint initiative between the Purdue colleges of agriculture and engineering in development of advanced sensing technologies and analysis methodology for wheeled and UAV platforms, focused on high throughput phenotyping for plant breeding.

Dr. Crawford is a Fellow of the IEEE, Past President of the IEEE Geoscience and Remote Sensing Society, an IEEE GRSS Distinguished Lecturer, and the current Treasurer of the IEEE Technical Activities Board. She was a member of the NASA EO-1 Science Validation team and served on the NASA Earth System Science and Applications Advisory Committee and the advisory committee to the NASA Socioeconomic Applications and Data Center (SEDAC).

Alex Gaeta

Columbia University

Chip-Based Comb Spectroscopy

The ability to generate optical frequency combs in microresonators at milliwatt power levels offers the promise for high-precision spectroscopic instruments in highly robust, compact, and portable platforms.

Peter Russo

Analog Photonics

High Performance Optical Phased Array LiDAR

Integrated optical phased arrays provide an attractive solution to LiDAR sensors by enabling solid-state, small-form-factor systems fabricated on 300mm wafers. We present recent results including high-performance beam steering and long-range LiDAR up to almost 200m."

About the Speaker

Peter Russo is Director of LiDAR at Analog Photonics. He received his Bachelor of Science in Electrical Engineering from University of Maryland, College Park in 2008. After graduating, he joined BAE Systems as part of the Engineering Leadership Development Program, through which he also received his Master of Science in Electrical Engineering from University of New Hampshire. At BAE Systems, he served as principle investigator on several active electro-optical systems programs. In 2015, he joined Formlabs, a 3D-printing startup, as a member of the electro-optical team.
