Stokes vector based polarization resolved second harmonic microscopy of starch granules

Investigating starch gelatinization through Stokes vector resolved second harmonic generation microscopy

The changes of the morphology during heating and the degree of crystallinity of dry and hydrated starch granules are investigated using second harmonic generation (SHG) based Stokes polarimetry. A spatial distribution of various polarization parameters, such as the degree of polarization (DOP), the degree of linear polarization (DOLP), and the degree of circular polarization (DOCP) are extracte...

Corrigendum: Investigating starch gelatinization through Stokes vector resolved second harmonic generation microscopy

Revealing molecular structure and orientation with Stokes vector resolved second harmonic generation microscopy.

We report on measurements and characterization of polarization properties of Second Harmonic (SH) signals using a four-channel photon counting based Stokes polarimeter. In this way, the critical polarization parameters can be obtained concurrently without the need of repeated image acquisition. The critical polarization parameters, including the degree of polarization (DOP), the degree of linea...

Polarization-resolved second harmonic generation microscopy with a four-channel Stokes-polarimeter.

We developed a four-channel photon counting based Stokes-polarimeter for spatial characterization of polarization effects in second harmonic generation (SHG). We have implemented a calibration technique allowing quantitative measurement of polarization parameters, such as the degree of polarization (DOP), degree of linear polarization (DOLP), degree of circular polarization (DOCP), as well as a...

Effect of molecular organization on the image histograms of polarization SHG microscopy

Based on its polarization dependency, second harmonic generation (PSHG) microscopy has been proven capable to structurally characterize molecular architectures in different biological samples. By exploiting this polarization dependency of the SHG signal in every pixel of the image, average quantitative structural information can be retrieved in the form of PSHG image histograms. In the present ...
