"The identification of the sign and strength of disclinations in the schlieren (nucleated domain) texture of the nematic phase, by optical microscopy."

Helen F. Gleeson, Ethan I L Jull and John E. Lydon



Each image was taken using a 50x objective. As the sample was rotated between 0? and 90? an image was taken at 5? intervals. 

Each of the six brush angles were then measured on each image using ImageJ software.

The rotation speed of the brush's were then compared with the sample rotation speed and the resulting average of 0.32 indicates that the defect is of s=+3/2.
