Soltrace based alignment Target Design Method for Concentrative Dish

By utilizing the Global-Stage-Element coordinate systems provided by Soltrace, dishes composed of mirror facets that form parabola shape can be modeled and adjusted. Combining the integrated light tracing method of the software, this paper provides a way to design target positions of reflected light from mirror facets, which is used to guide dish alignment in order to get required heat source. Theoretical analysis shows that the presented method can easily integrate dish structure and give highly concentrated evenly distributed heat source on the receiver plane without any lose of energy at the entrance of the receiver. Practical dish alignment done with the target positions validates our method.
