Resolution improvement in microscopic imaging through turbid media based on differential polarization gating

摘要

We report a new method for microscopic imaging of an object embedded in a turbid medium, based on the differential polarization-gating mechanism. It is demonstrated that with this method, image resolution through Optically thick milk suspensions can be improved by as much as 30% compared with no-gating methods. An image resolution of tens of micrometers is achieved in an optically thick turbid medium, which is approximately 10 times better than that achieved in transillumination imaging in a similar medium. # 1998 Optical Society of America OCIS codes: 110.7050,110.0180,260.5430.
