Polarimetry has widespread applications within atmospheric sensing, telecommunications, biomedical imaging, and target detection. Several existing methods of imaging polarimetry trade off the sensor’s...
Simple Method to Measure the Third-Order Nonlinear Coefficient of Optical Fibres
Third-Order Nonlinear Coefficient Optical Fibres
2015/7/16
We report a new method to measure the third order Kerr coefficient of optical fibres. This method is based on the self-phase-modulation-induced spectral broadening of optical pulses.
Digital speckle correlation method used to measure blood flow velocity
