A new multiple camber trough solar collector and its working principle have been introduced. By constructing a 3D model on computer and using an optical analysis software, the ray tracing of the solar concentrating system with flat receiver and cylindrical receiver, respectively, have been analyzed, and the relationship between the receiving beam and the incident ray has been investigated. By light tracing simulation, the distribution, width, eccentric magnitude of the image and efficiency of the concentrated light varying with the incident angle could be achieved and visualized. Also, the concentration ability of the system with flat receiver and cylindrical receiver, respectively, has been discussed and the comparison has been made with a quantitative result.
