Cool Images, Big Potential: Startup Uses Lasers to Create 3D Imagery

16 Oct

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.

Besides the cool effect, Hall said the imagery has real value. Researchers will be able to use the enhanced, high-contrast images to examine slight differences in samples. The process works faster, and is less labor intensive and possibly less expensive than current solutions on the market.

In a release sent out by Penn State’s Materials Research Institute, Hall said:

“This is a tomography technique, and there are others out there.  But x-ray tomography basically works by mapping the density of a substance, which is great unless the specimen has different materials of similar density. That can make it hard to differentiate structures, so it can be difficult to quantify measurements. Magnetic resonance imaging (MRI) we’re not even competing with. Those machines are so big and complex, and so expensive to operate compared to our system.”

Penn State has applied for a patent on the process. Meanwhile, Hall and his business partner Brian Reinhardt, a former Penn State graduate student, have created a startup, Lasers for Innovative Solutions (L4IS), to help companies, particularly agribusinesses, with high throughput phenotyping of their new products.

This is also a great example of a total team effort in preparing Penn State technology for market.

From the release:

“Included on the patent are Hall and his Penn State advisers, Jonathan Lynch and Ted Reutzel. Hall is currently working with Lynch on a paper describing their method. Ben Franklin Technology Partners of Central and Northern Pennsylvania provided funding and business assistance to start the company, and the Ben Franklin TechCelerator @ State College provided valuable entrepreneurial training.”

    Cool post! Wish we could blow up those pix.
