ABSTRACT
The formation of cross-sectional images of biological
tissues requires the discrimination between light conveying useful
information-that is, propagating directly from object to image-
from the abundant parasitic light caused by multiple scattering
inherent to turbid media [1, 2]. In optical coherence tomography
(OCTa) [3], selective detection of light undergoing a single backscat-
ter event (reflection imaging) and rejection of multiply scattered
light (MSL) has been successfully achieved by combining temporal
coherence gating and confocal spatial filtering [4, 5].
