Dear Readers, We would like to present, with great pleasure, the Eighth volume of a scholarly International Journal of Optical Sciences. This journal is part of the physics, and is devoted to the scope of present physics issues, from theoretical aspects to application-dependent studies and the validation of emerging technologies. This journal was planned and established to represent the growing needs of International Journal of Optical Sciences as an emerging and increasingly vital field, now widely recognized as an integral part of scientific and technical investigations. Its mission is to become a voice of the Physics community, addressing researchers and practitioners in this area.
