Abstract

Optical Coherence Tomography (OCT) is an imaging technique that performs high-resolution transverse and axial imaging of samples. We demonstrate a novel mechanical-scan free Spectral Domain OCT scheme that performs axial and transverse scans of the sample avoiding the use of any kind of mechanical platforms. The scheme makes use of a spatial light modulator in combination with some simple optical elements. This proof-of-principle demonstration can help usher in the development of alternative OCT schemes with potentially faster scan speeds than current OCT schemes by avoiding the use of any kind of mechanical platforms.
