Laser Speckle Contrast Imaging on RaspberryPi -Done

Project supervisor: Yoav Hazan

Laser Speckle Contrast Imaging (LSCI) is an imaging method used in diffusive media. This method maps the regions of dynamic scatters, i.e. blood flowing in blood vessels. Due to developments in both cameras and miniaturized computers, LSCI systems may be implemented in a small cost efficient system, such as a RaspberryPi platform.

Project Status: Taken

Raw image of part of a rat cortex (a) and its LSCI version (b). Briers et al., 2013

Project requirements:

  1. Implementing stand-alone LSCI system on a RaspberryPi platform.
  2. Researching LSCI from high frame rate video. Theoretical analysis and modeling of the new measured field mapped by high frame rate LSCI.

Advancement options:

  1. Researching bi-spectral LSCI.
