We demonstrate a nonscanning approach for cross-sectional imaging based on optical coherence-domain reflectometry. Using an angular dispersion imaging scheme, wide-field depth-resolved images are acquired at video rate wide an image sensor.
We demonstrate phase-drift suppression (PDS) to enhance stabilization of the computed signal intensity (CSI) in heterodyne detection without optical and/or electronic feedback systems. CSI is defined as the square root of the sum of the squares of each harmonic intensity in the heterodyne beat signal. The PDS theoretically and experimentally demonstrates stabilizing conditions for modulation indexes...
