Polarization anisotropy of sarcomeric SHG. (A) Schematic showing the relative orientation of the specimen and the propagation and polarization axes of the excitation laser beam. (B) Profile of SHG intensity versus the relative angle of scallop myofibrils to laser polarization axis. Inserts show changes of SHG intensity with rotation relative to a fixed laser polarization. Error bars show mean ± SD. (C) Comparison of the polarization anisotropy of scallop striated myofibril and obliquely striated C. elegans body wall muscle. Error bars show mean ± SD.
