Abstract

We present an optical imaging system, termed Spatio-Temporal Optical Coherence Tomography, for high-resolution and fast in vivo imaging of chorioretinal complex. The system utilizes a fast camera and a swept laser source for fast volumetric data acquisition. A multimode fiber is used to break the spatial coherence of the laser that reduces the crosstalk noise in the OCT images. We choose the fiber parameters such that it gives the most optimal images in terms of signal strength, resolution and crosstalk reduction. We also test combinations of the fiber with other optomechanical devices in the attempt to further improve the images.
