Workshop Option 1
Low Uncertainty and the Calibration Life Cycle for New Space
Labsphere will discuss the challenges of low uncertainty from the perspective of the “calibration life cycle” and the requirements on the radiometric calibration artifacts. We will discuss some of the things that can be done pre-launch that are towards 1% uncertainty and some of the challenges in these calibrations. This will begin with a discussion on radiometry, calibration traceability, calibration methods, and conclude with uncertainty considerations and methods.
The change in the industry today seeks not just to perform characterization and calibration for a single satellite, but many, during a given launch. Also, instrument fleets are comprised of many generations of the “same” satellites and maintaining interoperability and harmonization between these different generations is also a challenge. How can calibration scale and still be economical? Does this better calibration bring more value to the product for a more attractive ROI?
We will introduce the concept of a “Calibration Life Cycle” to help answer these challenges. Much of these considerations start with a with design concept and inclusion of architectures ideas that are easy to validate and are stable and repeatable under mission life conditions. Thought must then be given to what types of testing are needed on the ground to know “enough” about the satellite to sustain performance. Once on orbit, how can the fleet be calibrated and harmonized? How can different fleets harmonize with each other and achieve interoperability of data? What can we learn from performance in one generation to the next and how can that make data and calibration better? Calibration in all phases of satellite life need to be given priority at a program level to achieve high quality and traceable data from constellations.
Dr. Dan Scharpf, Chief Technology Officer, Labsphere
Dr. Scharpf has been with Labsphere for twelve years with roles spanning Sales, Engineering Management, and Executive Management. He has contributed to the design of standard and custom systems for Labsphere’s full range of products including light metrology, remote sensing systems, and diffuse targets. Prior to joining Labsphere Dr. Scharpf worked at ANSYS and Boeing where he was involved in testing, modeling, and analyzing engineering solutions in the areas of fluid dynamics, turbomachinery, acoustics, thermal management, and uncertainty. He holds a bachelor’s degree in mechanical engineering from the University of Dayton and master’s degree and PhD in aerospace engineering from the University of Notre Dame.
Chris Durell, Sales Director, Labsphere
Chris Durell holds a BSEE and an MBA and has worked for Labsphere, Inc in many executive capacities. He is currently leading Business Development for Remote Sensing Technology. He has led product development efforts in optical systems, light measurement, and remote sensing systems for over two decades. Chris accepted the inaugural Chair position for the IEEE P4001 Hyperspectral Standards Working Group in 2018.
Workshop Option 2
Radiometry & SBIR Test Capability Test Capability Overview
Santa Barbara Infrared will present an infrared radiometer overview with radiometric concepts and figure of merits as related to SBIR’s spectro-radiometric test equipment and software capability. Topics include radiometry description, comparison of radiometric and thermometric measurement, why to use radiometric measurements and why all measurements are not radiometric. Some of the radiometric figures of merit that are discussed are Noise Equivalent Radiance (NER), Noise Equivalent Irradiance (NEI), Noise Equivalent Flux Density (NEFD), Noise Equivalent Power (NEP), and D* (specific detectivity).
Dr. Arn Adams, Chief Technical Officer, IRCameras, LLC
Arn Adams received Physics PhD in 1980 from UC Santa Barbara and has helped develop thermal infrared detectors and cameras ever since at Santa Barbara Research Center (now Raytheon Vision Systems), Santa Barbara Focalplane and IRCameras. Arn improved detector performance at both SBRC and SBF, developed the first Windows software for infrared cameras (still actively developed as WinIRC), helped develop the first high speed digital-output FPAs, and helped found IRCameras to help satisfy the need for both off-the-shelf and highly-custom IR cameras across the SWIR-MWIR-LWIR spectrum.
