Title: High Power, Configurable, Picosecond LED Drive
Invention: This technology uses an LED to achieve the same imaging results as a laser source, without damaging the tissues.
Background: Laser sources are the current standard in fluorescent imaging techniques, but lasers can damage tissue samples over time. The technology presented here is based on a technique used in high energy physics for scintillation counting, which optimizes the transient recording of fluorescence using the gating paradigm of photomultiplier tubes (PMT) for use in biology. Therefore, this technology is powerful enough to accomplish what current laser excitation can, without the tissue damage over time.
