Abstract

Owing to the fast-acquisition times and long-imaging ranges provided by swept-source optical coherence tomography (SSOCT), it has seen widespread commercial success in a wide range of real world applications. However, the high-cost and bulky size of swept-source lasers limits the potential application range of the technology. Here, a SS-OCT system utilizing a low-cost and compact wavelength-tunable laser designed for telecommunications is presented. The limited tuning range and discontinuous tuning of the telecommunications laser, is overcome through the use of compressed sensing, enabling the acquisition of OCT scans with enhanced resolutions and signal-to-noise ratios.
