Optical System Design Method Based on Rotating Risley Prism

IEEE Photonics Journal
As a type of beam steering element, the Risley prism has found extensive applications in the field of optics. A single Risley prism can deflect incident light beams with a constant deviation angle, while a rotating multi-Risley prism system enables ...

Optimization of SPR signals: Monitoring the physical structures and refractive indices of prisms

EPJ Web of Conferences, 2017
Surface plasmon resonance (SPR) can only be achieved if sufficient energy is provided at the boundary between metal and dielectric. An employment of prism as a light coupler by using Kretschmann configuration is one of the alternative for the production ...
