We present a flexible OCT engine for acquiring full eye-length, anterior and posterior segment B-scans, as well as 4D live volumes with an effective A-scan rate of up to 2MHz. It is enabled by a MEMS tunable VCSEL with flexible A-scan rates, broad spectral bandwidth and a long instantaneous coherence length. Our GPU based, custom reconstruction and rendering software is able to process and display live volume series at rates of up to 17 volumes per second. We show B-scans and volume series of model eyes.
