Abstract
Abstract
Measuring depth-resolved birefringence traditionally requires at least two distinct input polarization states. We identified a constraint on the evolution of the polarization state as a function of the round-trip path-length into birefringent tissue that enables to recover comparable results using only a single input state.

Abstract
We demonstrate a method to reconstruct confocally gated reflection images acquired through a multimode fiber. It requires a series of distinct illumination patterns obtained by varying the proximal coupling of the illumination and enables fast volumetric imaging without physically focusing the light into the sample.
