Sub-second A-scan Acquisition Using Marginal Spectral-Domain Quantum Optical Coherence Tomography
P. D. Yepiz-Graciano, D. Salamanca-Roldán, H. Cruz-Ramírez +2
We report an optimized implementation of spectral-domain quantum optical coherence tomography (SD-QOCT) capable of acquiring axial scans (A-scans) of multilayer samples without in…
