WebIn this paper, a robust control based on disturbance observer is proposed to improve the tracking accuracy of the Risley prism system (RPS). Applying the flexible thin-wall ring mechanism in the RPS causes a series of tracking and pointing challenges. Disturbances such as friction, shaft deformation, and model perturbation significantly deteriorate the … WebREO can fabricate Risley prism pairs from a number of different materials suitable for operation at wavelengths throughout the ultraviolet, visible or infrared spectral ranges. Typical examples include fused silica, optical glasses, CaF2, ZnS, ZnSe, Ge and Si.

"WebOne unique aspect of Risley Prisms is the scanning pattern they can create. The pattern will change depending on the direction of rotation of each wedge prism and their relative angular velocity with respect to each other. In general, a Risley Prism will create a series of patterns called Rose Curves. Two of these patterns are shown in figure 1. " - Risley's electronics
