In this report, we describe the implementation of an angle-gating
mechanism into a reflection optical microscope for imaging through a
turbid medium. A significant improvement in image resolution and contrast
is obtained when a polarizing annular objective is used to image a
reflective test bar through various turbid media. The experimental results
confirm that the improvement is caused by the efficient suppression of
diffused photons scattered from the turbid medium when a polarized annular
objective is employed as an angular gate.
