摘      要：A flux density distribution measurement system for rotating parabolic concentrators is designed and developed. The pictures of the distribution on focal plane and other defocused planes of the concentrator are taken by using an indirect method with a Lambert target and a CCD camera. The pictures are saved and processed by computer. The calibration method of system is introduced and the spot distribution picture of focal plane is presented. The measurement result is compared with the calculated result by Monte Carlo method. At last, the main system errors are analyzed. The experiment results show that the measurement error of flux density is 6.85%.
