Abstract: | Using a monochromatic light source for illumination, a new approach is proposed which uses two different loads to get continuous isoclinic fringes. A new set of optical arrangements in a plane polariscope setup is proposed for this purpose. The intensity equations are obtained by Jones calculus. The methodology is verified for the problem of a disc under diametral compression. |
