  Spatiotemporal optical coherence (STOC) imaging is a new technique for
suppressing coherent crosstalk noise in Fourier-domain full-field optical
coherence tomography (FD-FF-OCT). In STOC imaging, the timevarying
inhomogeneous phase masks modulate the incident light to alter the
interferometric signal. Resulting interference images are then processed as in
standard FD-FF-OCT and averaged incoherently or coherently to produce
crosstalk-free volumetric OCT images of the sample. Here, we show that coherent
averaging is suitable when phase modulation is performed for both
interferometer arms simultaneously. We explain the advantages of coherent over
incoherent averaging. Specifically, we show that modulated signal, after
coherent averaging, preserves lateral phase stability. This enables
computational phase correction to compensate for geometrical aberrations.
Ultimately, we employ it to correct for aberrations present in the image of the
photoreceptor layer of the human retina that reveals otherwise invisible
photoreceptor mosaic.
