Overcoming light scattering: New optical system sees deeper inside tissue
Date:7/2/2014

Optical imaging methods are rapidly becoming essential tools in biomedical science because they're noninvasive, fast, cost-efficient and pose no health risks since they don't use ionizing radiation. These methods could become even more valuable if researchers could find a way for optical light to penetrate all the way through the body's tissues. With today's technology, even passing through a fraction of an inch of skin is enough to scatter the light and scramble the image.

Now a team of researchers from Spain's Jaume I University (UJI) and the University of Valncia has developed a single-pixel optical system based on compressive sensing that can overcome the fundamental limitations imposed by this scattering. The work was published today in The Optical Society's (OSA) open-access journal Optics Express.

"In the diagnostic realm within the past few years, we've witnessed the way optical imaging has helped clinicians detect and evaluate suspicious lesions," said Jess Lancis, the paper's co-author and a researcher in the Photonics Research Group at UJI. "The elephant in the room, however, is the question of the short penetration depth of light within tissue compared to ultrasound or x-ray technologies. Current knowledge is insufficient for early detection of small lesions located deeper than a millimeter beneath the surface of the mucosa."

"Our goal is to see deeper inside tissue," he added.

To achieve this, the team used an off-the-shelf digital micromirror array from a commercial video projector to create a set of microstructured light patterns that are sequentially superimposed onto a sample. They then measure the transmitted energy with a photodetector that can sense the presence or absence of light, but has no spatial resolution. Then they apply a signal processing technique called compressive sensing, which is used to compress large data files as
