Personal Webpage of Andreas Velten

I am an Assistant Scientist in the Medical Devices Group at the Morgridge Institute for Research and the Laboratory for Optical and Computational Instrumentation (LOCI) at the University of Wisconsin, Madison. I obtained my PhD in Physics at the University of New Mexico designing lasers for ultra sensitive phase measurements.

I was chosen as one of the 35 top innovators under the age of 35 by MIT's Technology Review in 2012, received the Popular Mechanics Breakthrough Award in 2012, and was included in the 2013 SME innovations watchlist.

My research focuses on Applied Computational Optics and Imaging. Creating and analyzing an image from electromagnetic waves involves at the same time data collection and processing. In all imaging systems these tasks are inseparably interconnected. Both the process of image formation, and the analysis of images can be performed optically, digitally or using a combination of both.

I develop integrated cyber-physical imaging systems combining illumination, data collection, image formation, and image processing into one integrated unit. This allows us to build imaging systems that detect specific application relevant information in the huge amount of accessible optical data with the best possible signal to noise ratio. My work spans research in photonic devices, optical systems engineering, optimization, computer vision, and biomedical applications.

Through their greater flexibility, Computational Imaging systems can access information that is not accessible through traditional imaging methods. In particular, I am developing methods to detect morphological changes in the extracellular matrix that accompany breast cancer progression. Tracking such changes will enable non-invasive early cancer detection, will help improve our understanding of cancer onset and metastasis, and accelerate the development of a cure.

I also develop remote sensing and biomedical imaging technologies that are based on non-traditional time-of-flight based image formation methods. Being able to create images from multiply reflected indirect light, these systems can see around corners and into inaccessible spaces. This makes it possible to locate and diagnose individuals in disaster areas and to image the inside of lunar caves. It also has applications in endoscopy and robotic surgery.

The image is a reduced spectral and spacial resolution version of the data captured by our new high speed hyperspectral multipoint confocal microscope that captures images with 15 spectral channels at up to four frames per second.
