Paper Abstract

By increasing the speed and reducing the complexity of OCT systems, the parallel OCT system presented here will reduce the cost of high performance instruments while making them more widespread and easy to use. The instrument integrates line scanning with a swept source to achieve ultrahigh image speeds in a much simpler way. The swept source speed requirements are significantly relaxed. In a traditional OCT, a focused beam is scanned for image formation, while parallel OCT images simultaneously a full B-scan or a complete 3D cube. The system achieved ultrahigh scan speeds (98 kHz line rates and 160 fps), and was initially tested on various reflective and diffuse targets. The system demonstrates the potential for 3-D volumetric mapping of tissue at several volumes per second.
