IBS researchers develop high-resolution “ultra-thin” endoscope

Researchers at the Institute for Basic Science (IBS) say they developed a high-resolution holographic endoscope system.

Choi Wonshik, associate director for the Center for Molecular Spectroscopy and Dynamics (CMSD) within IBS, led the team. According to a news release, the researchers overcame the previous limitation of fiber optic endoscopy. They reconstructed high-resolution images without attaching a lens or any equipment to the distal end of the fiber bundle.

The researchers say general endoscopy attaches a camera sensor to the end of a probe using an optical fiber. With camera sensors, the probe thickness increases, making the endoscopy rather invasive. Manufacturing in a thinner form factor can minimize invasiveness and thus patient discomfort. However, a conventional fiber bundle endoscope struggles to perform high-resolution images because the size of the individual fiber …
