University of Pennsylvania Background
Light-sheet fluorescence microscopy enables rapid scanning of biological samples to reconstruct a 3-dimensional image of the sample. However, images generally contain artifacts (shadows, stripes, etc.) that are caused by illumination inhomogeneity due to absorption or scattering within the sample. These artifacts can occlude observation of biological phenomena in a sample. Moreover, current products use expensive and technologically demanding instrumentation to address these issues.
Researchers at the University of Pennsylvania have developed methods to passively generate multidirectional illumination in a light-sheet imaging system using a light shaping diffuser. The outcomes include the elimination of optical artifacts, similar to those described above. An add-on device incorporating this method into an optical microscope would provide a cost-effective alternative to current prohibitively expensive stand-alone equipment.
