A New Volumetric Eye: Light Field Microscopy

Light field cameras instantaneously capture a volume by recording both the location and the angle of photons arriving at a camera sensor. This means that each camera exposure results in a 3D structure, visualized through panning sequences, focal stacks, or volume renderings. Recently, my colleagues and I have applied this technique to microscopic objects. In this talk, I will describe our microscope and present examples from marine biology, particularly 3D neural activation patterns in the zebrafish brain (for instance: http://www.stanford.edu/~tanders/lightfield/mcknight/vis-stim/vis-stim.html). In addition, I will describe a concept for a classroom version which would allow interactive 3D exploration of microscopic specimens from anywhere with an internet connection.
