Abstract

Abstract

En 中文
• Our BD-SD-OCT achieves 2× signal intensity, +5dB SNR, and >10dB DC/AC suppression vs single SD-OCT. • Hardware-free spectral calibration is achieved via source-noise-based correlation. • Full-range OCT using dispersion encoded and energy centrobaric correction method. • Industrial BD-SD-OCT with generic SLD: cost-effective, high-performance.
