An overview of inverse solution expressions for Risley-prism-based scanner

The paper overviews the advantages and disadvantages of various inverse solutions methods for the Risley-prism-based scanner. According to some given target trajectories, the calculation precisions and calculation consuming time by four different inverse solution methods are investigated, respectively, which reflect the computing complexities and condition applicability. Meanwhile, the corresponding scanning precisions for the same target trajectory by four methods are compared to each other. The paper overviews the limits of different inverse solution methods and evaluates different inverse solution methods for specific beam scanning applications.
