WebAt the heart of a Risley prism system is a pair of matched glass wedges in series. Based on the simple principle of refraction that results in the bending of light as it passes from one media to another, a glass wedge bends the incident light beam in air at an amount proportional to the wedge angle. WebOPTRA has recently developed Risley-Prism based solutions for compact laser beam steering applications. Risley prism beam steering systems are smaller, use less power, and weigh less than conventional gimbal-based beam steering systems, which makes them more immune to vibration and able to achieve higher response times and beam steering …

WebA pair of wedge prisms, called a Risley prism pair, can be used for beam steering. In this case, rotating one wedge in relation to the other will change the direction of the beam. When the wedges angle in the same direction, the angle of the refracted beam becomes greater. WebMar 28, 2024 · We present a low-profile, mechanically beam-steerable antenna that implements the Risley prism beam-steering concept using only a single flat prism. The proposed antenna achieves 2-D beam steering and consists of two parts: a holographic leaky-wave antenna and a phase-shifting surface (PSS) that acts as a flat prism. The … dalkeith road ilford
