High-throughput optical coherence tomography at 800 nm by Keisuke Goda, Ali Fard, Omer Farooq Malik, Gilbert Fu, Alan Quach, Bahram Jalali.
We report high-throughput optical coherence tomography (OCT) that offers 1,000 times higher axial scan rate than conventional OCT in the 800 nm spectral range. This is made possible by employing photonic time-stretch for chirping a pulse train and transforming it into passive swept source. demonstrate record high of 90.9 MHz. To show utility our method, we also real-time observation laser ablation dynamics. Our expected to be useful industrial applications where speed falls short.
