Recently, High-times Concentrating Directional Transmission System (CDTS) was built in the authors’ laboratory. To evaluate the focal flux distribution of a solar concentrator, a kind of measurement system was established, in which an infrared camera and several thermocouples along with a heat flow meter were employed, and the clear heat flux distribution of focal spot was obtained. The skew ray tracing principle was used to simulate the process of solar energy transmission and compared with the test results.Keywords: measurement and instrument, CDTS, heat flux distribution, skew ray tracing principle ER -
