摘要：

Data compressed photonic time stretch optical coherence tomography system enables high speed signal detection with reduced bandwidth requirement for backend electronic and digitizers. However, the measurement resolution is inherently dependent on the repetition rate of mode-locked laser. This work reports a new approach to improve depth profile resolution based on dual pulse integration. In our experimental demonstration compression ratio of 66% is achieved and depth resolution is improved by two fold.
