Volumetric Imaging Application Note

Overview: In order to understand biological functions at a system level it is necessary to image
interconnectivity of processes in real time. This is particularly relevant in neuroscience, where the BRAIN initiative is funding research to understand how the brain functions, and how that function is altered by disease. This requires imaging with single cell resolution within a volume as large as possible. There are multiple approaches to volumetric imaging. Light sheet microscopy enables low intensity illumination across a plane of the sample such that large field of view imaging with minimized optical heating is achieved. Similarly scanning a Bessel beam throughout a volume enables compression of a volume of activity into a single plane for deep tissue large field-of-view high-speed imaging.
