In this paper it was designed a new fractal optical modulation by using a new iteration of fractal function. the result was analyzed by MTF evaluation. and it compared with results of normal optical modulation. The normal and fractal optical modulator is a circular disc which has a radius R=9cm. https://www.roneverhart.com/Lifestyle-Mobility-Aids-P2-Portable-Oxygen-Concentrator-with-Carry-Case/
