Some recent progress in hemispherical electronic eye cameras and related devices
Digital camera systems that incorporate bio-inspired designs can provide certain advantages in imaging compared to conventional devices. One concept uses photodetector arrays on hemispherical surfaces, as analogs to retinas in mammalian eyes, instead of standard planar layouts. From a practical standpoint, such non-planar geometries can be difficult to achieve, due to the intrinsically planar nature of established fabrication techniques for electronics/optoelectronics. This talk describes approaches that combine stretchable arrays of photodiodes, fabricated in planar geometries using established fabrication techniques and then reshaped into the desired curvilinear configurations as a final step. We summarize features of several types of cameras that we have built using this process, including their imaging characteristics revealed by experiment and modeling. Results range from hemispherical to parabaloid devices, to those with tunable layouts and optimized mechanical designs.

The Future of Light and Lighting
LEDs have continued to improve rapidly in efficacy and cost making them increasingly used in a wide variety of illumination and display applications. Already, the efficacy commercial lighting fixtures are well beyond many traditional lighting sources and LEDs are quickly moving towards and past fluorescent technology. In addition to their light output, the quality and color of these light sources is also approaching and even surpassing traditional sources. With the LED, this future of light now offers unprecedented control of light, color, radiance, spectral power distribution and more. Many examples of the use and power of LEDs will be shown and especially how LEd lighting can transcend traditional lighting.
BIO: Kevin joined MC10 as the VP of R&D in January of 2010. Prior to MC10, Kevin was VP of Innovation at Philips Color Kinetics where he oversaw many programs and initiatives designed to keep Color Kinetics at the forefront of LED lighting. Previously he built and led the engineering team at Color Kinetics and was active in a variety of strategic roles in technology development, intellectual property, Color Kinetics' IPO in 2004 and acquisition by Philips in 2007 for $800M. He also proposed and led significant programs for the Department of Energy and NIST as well as helping develop the first entrant by Philips for the DoE $10M L-Prize. Kevin actively engaged with government and industry and was co-founder and Chairman of the National Electrical Manufacturers Association (NEMA) Solid-State Lighting Section and the Illuminating Engineering Society (IES) Solid-State Lighting Committee. He was also Chairman of the Next Generation Lighting Industry Alliance (NGLIA). Prior to Color Kinetics, Kevin was Chief Robotics Engineer for PRI Automation, developing advanced factory automation systems for the semiconductor industry. He has over 15 years of experience in advanced robotics engineering at the Robotics Institute at Carnegie Mellon University, where, as a scientist, he led many projects including robotic systems for a Lunar Rover demo, Space Shuttle inspection at NASA's Kennedy Space Center, and the Mars Rover Project. He holds 60 U.S. Patents and is the recipient of numerous awards and fellowships. Kevin received his BS in Mathematics and MS and Ph.D. degrees in Robotics from Carnegie Mellon University.

Projectors and Cameras for High Dynamic Range Imaging
The power of the human visual system to process wide ranges of intensities far exceeds the abilities of current imaging systems. Both cameras and displays are currently limited to a dynamic range (contrast) of between 300:1 to 1,000:1, while the human visual system can process a simultaneous dynamic range of 50,000:1 or more, and can adapt to a much larger range. High Dynamic Range Imaging seeks to address this situation by developing a new imaging pipeline that more closely matches the characteristics of the human visual system. In this talk I will present some recent progress and current work on creating HDR cameras and projectors. On the camera side, I will take a computational photography view by optically encoding HDR information into a low contrast image that can be captured with standard image sensors and decoded in software. On the projector side, I will outline a new light reallocation projector design based on experimental MEMS technology.
BIO: Associate Professor Wolfgang Heidrich holds the Dolby Research Chair in Computer Science at the University of British Columbia. He received a PhD in Computer Science from the University of Erlangen in 1999, and then worked as a Research Associate in the Computer Graphics Group of the Max-Planck-Institute for Computer Science in Saarbrucken, Germany, before joining UBC in 2000. Heidrich's research interests lie at the intersection of computer graphics, computer vision, imaging, and optics. In particular, he has worked on High Dynamic Range imaging and display, image-based modeling, measuring, and rendering, geometry acquisition, GPU-based rendering, and global illumination. Heidrich has written over 90 refereed publications on these subjects and has served on numerous program committees. He was the program co-chair for Graphics Hardware 2002, Graphics Interface 2004, and the Eurographics Symposium on Rendering, 2006.
