Birefringence imaging
WebIn recent years we have developed rapid technologies that detect the location of the fovea using retinal birefringence scanning (RBS). Yet, combining it with ophthalmic imaging technologies is not trivial, mainly because RBS employs polarized light and polarization-sensitive optics, while most ophthalmic imaging systems do not. WebQuantitation of the colors seen in birefringent samples is commonly provided by means of the Michel-Levy chart illustrated in Figure 5 above. As is evident from this graph, the polarization colors seen in the microscope …
