Describe the structure of a collagen molecule
WebSecond harmonic generation (SHG) microscopy is an effective analytical tool for a detailed investigation of the microscopic structure of non-centrosymmetric molecules. We developed a four-channel photon-counting-based Stokes polarimeter integrated to the SHG microscope for spatial characterization of polarization effects in the SH signal.
