A laser that creates a three-dimensional picture of a bee’s head may sound like an experiment being conducted in Dr. Evil’s super-secret volcano base, but this technology is blossoming right here at Penn State — and it has real-world applications for research in agriculture and horticulture.
At a recent talk at the Millennium Science Complex, Benjamin Hall, an undergraduate student in energy engineering working part-time in the laser lab of the Applied Research Laboratory at Penn State, discussed the technique — and showed images and videos that rival most Hollywood special effects. By placing an object, such as a plant root, on a moveable platform that passes under a laser, researchers can vaporize the sample section by section. The technique creates a series of surface images, which Hall then processes with a software program to create three-dimensional interior and exterior — and unbelievably cool — images of the sample.
