    Abstract: A new model of Cascaded Black – Linear Distribution (CBLD) in circular aperture is suggested. Four different models of CBLD are studied. In the 1st model, ten strips are considered where half of them are black and the other half has linear distribution, starting with black strip from the center of the circular aperture. In the 2nd model, twenty str... Show More

    Abstract: A manipulation of four circles arranged along the Cartesian coordinates in uniform circular aperture is compared with selected four blood cells forming the object using the technique of speckle photography. The aperture model is considered have two- fold symmetry. A diffuser is placed in the same plane of the object or the model of four circles in ... Show More
