The purpose of this work is to develop a method to generate external k-clock sampling signals, which provides enhanced depth ranges up to 13.8 mm with commercial reflective Fabry-Perot tunable laser type SS light sources. The strategy to enhance the depth range is to purify the k-sampling clock using electrical filters. We found two depth ranges and one optical delay length, where enhanced depth ranges can be attained. We observed PSFs and OCT images at three selected depth ranges of 6.7, 11.5 and 13.8 mm using newly developed external k-sampling-clock generator. OCT imaging of entire anterior segment of a human eye are demonstrated with depth ranges 11.5 and 13.8 mm.
