Abstract

Full volumetric high speed OCT imaging of the retina with multiple settings varying in volume size and volume rate is presented. The volume size ranges from 255x255 A-scans to 160x40 A-scans with 450 samples per depth scan. The volume rates vary between 20.8 V/s for the largest volumes to 195.2 V/s for the smallest. The system is based on a 1060nm Fourier domain mode locked (FDML) laser with 1.6MHz line rate. Scanning along the fast axis is performed with a 2.7 kHz or 4.3 kHz resonant scanner operated in bidirectional scanning mode, while a standard galvo scanner is used for the slow axis. The performance is analyzed with respect to various potential applications, like intraoperative OCT.
