A novel optical coherence tomography (OCT) system is presented that combines Fourier-domain OCT with incoherent nonlinear time gating. By processing backscattered light in the optical domain, the user can select a restricted depth field of view for improved contrast and acquisition speed. This technique has the additional advantage that imaging is done in the infrared (approximately 1280 nm) but is detected in the visible(approximately 504 nm).
本文介绍了一种新型光学相干断层扫描（OCT）系统，该系统将傅里叶域OCT与非相干非线性时间选通相结合。通过在光学域中处理背向散射光，用户可以选择受限的深度视场，以提高对比度和采集速度。该技术还有一个额外的优点，即成像在红外波段（约1280纳米）进行，但在可见光波段（约504纳米）进行检测。
