Development of the calibration device using UAV mounted UV-LED light source for the fluorescence detector
Abstract
We have developed a standard UV-LED light source mounted on an unmanned aerial vehicle (UAV), so-called the Opt-copter, for the calibration of the fluorescence detectors (FDs) of the Telescope Array experiment. The positioning accuracy of the UAV controlled by GPS is ~ 10 cm, which enables a precision calibration of the pointing directions of the FD phototubes. We report the hardware details of the device and the status of data analysis.
