Abstract

Optical Wireless Power Transmission (OWPT) is one of Wireless Power Transmission (WPT) technique which are developed to deliver electric power to long distance without using copper cable. In OWPT, laser or LED is used as the transmitter to convert electric power to light and solar cell is used as the receiver convert back light to electric power. Among the techniques of WPT, OWPT has advantage in term of its wide possible applications such as to send power through water and through human skin to charge implantable medical devices and its potential to deliver high intensity power to long distance by taking advantage of small beam size and small divergence angle of laser beam. However, additional device is needed to steer the laser beam. In this research, Galvano mirror is used to steer the beam to power up moving object. Camera with color segmentation method which is one of the techniques of OpenCV is used to recognize the target. Color marker is attached at the target. This color marker is recognized by the camera. In OWPT to 2-dimensional moving object, 2 color markers are attached at the moving target to solve position mismatch problem between camera and mirror. By taking advantage of the fast reaction of the Galvano mirror, OWPT to multiple moving objects using only one set of mirrors has been demonstrated. Periodic color segmentation method in which the recognized color is switched periodically is used in this demonstration.
