Optical Wireless Power Transmission ( OWPT) is one of methods that used to transfer the power from laser diode to an object for long distance. It provides a coherent almost non-divergent beam with high energy density in a small beam size of diameter. This condition makes the direction of the laser beam to the appropriate target using laser beam steering system is needed. In the previous, we have been successfully developed a beam steering system for one and two-dimensional object movement. In this research, we have challenged to improve the beam steering system to transmit the power for multi-object. In this case, we used the periodic color filtering method to transfer the power for two objects by modifying the recognizing time using the frame rate. As the result, the targets can change periodically move for every several frames in one-dimensional movement.
