SUMMARY:Imaging around obstacles and into lunar caves using scattered 
 light\, Chaos & Complex Systems Seminar\, Andreas Velten\, UW Departme
 nt of Molecular Biology
DESCRIPTION:The Computational Optics Group at the UW Laboratory for Op
 tical and Computational Instrumentation (LOCI) develops novel imaging 
 systems by combining new hardware designs with novel computational ima
 ge reconstruction methods. The traditional method of imaging is based 
 on hardware that resembles the human eye to produce images suitable fo
 r analysis and pattern recognition by a human viewer. A traditional ca
 mera like this only accesses a very small fraction of the information 
 provided by the light field. Most of the light detected by optical sys
 tems occurs in the form of multiply scattered photons that can not be 
 used to create an image in this traditional way. In this talk I will s
 how different systems that\, using custom methods to selectively captu
 re and control photon time of flight\, allow us to capture information
  inaccessible to a regular camera.<br><br>
\n<br><br>
\nOur Modular In
 direct Remote Imaging System (MIRIS) uses ultrafast illumination and d
 etection to collect and utilize light transport information. A laser i
 s used to direct a pulse train towards one of the visible surfaces in 
 a scene. The light bounces off of this surface and reflects off object
 s in the scene before heading back towards the visible scene where it 
 is imaged with high time resolution by a camera. Images of the scene a
 re reconstructed from the collected time-encoded information using a m
 odified backprojection algorithm.<br><br>

\nIn collaboratio
 n with the NASA Jet Propulsion Lab\, we are performing studies to appl
 y this method to explore the inside of caves on the moon from a low lu
 nar orbit.
