Optical coherence tomography (OCT) is a popular imaging modality for obtaining three-dimensional, micrometer-resolution pictures of structures that lie beneath the surface of, for example, the human eye or silicon wafers used in the computer industry. The technique could now become even more powerful, thanks to work led by Hon Luen Seck from the Singapore Institute of Manufacturing Technology at A*STAR. The team has found a way to eliminate one of the main noise sources that otherwise blur these images.
