Fluorescence emission difference microscopy based on polarization modulation

Journal of Innovative Optical Health Sciences, 2022
In this paper, we propose a new fluorescence emission difference microscopy (FED) technique based on polarization modulation. An electro-optical modulator (EOM) is used to switch the excitation beam between the horizontal and vertical polarization states

Refinements in Polarized Light Microscopy [PDF]

Journal of Experimental Biology, 1950
ABSTRACT Various measures to increase the sensitivity of the polarizing microscope for visual observation are discussed. These include choice of polarizing apparatus, reducing condenser and objective aperture, reducing lamp iris, blooming lenses, use of mica plate compensators and use of bright light sources. By such means as these it is
