Paper Abstract

A full-spectral monitoring (FSM) system utilizing (charged coupled device) CCD array spectroradiometer and optical fiber has been developed and implemented for accelerated laboratory weathering instruments. The system provides in-situ, real-time irradiance monitoring and control. Compared to the conventional photo diode and fixed band pass interference filter radiometer used for irradiance measurement and control, FSM represents a revolutionary step forward for the weathering industry. Additionally a calibration process utilizing an identical xenon lamp used for testing has been developed for the FSM system. This calibration process greatly simplifies the traditional Mercury plus FEL lamps based calibration process. The total measurement uncertainty of this FSM is also analyzed and discussed in the paper.
