Multiplexed fiber meta-tip-based circular polarimetry for label-free pathological analysis of ischemic stroke.

Significance: We present an optical technology for a full-process label-free method for brain slice screening. This proposed multiplexed circular polarimetric method has the advantages of simple operation and high accuracy which may provide easily accessible evidence for the future diagnosis of related diseases.

Aim: One of its missions is to provide a quantifiable, reproducible analysis methodology that can replace or supplement traditional qualitative, subjective pathological analysis.
