Objective: European alternative for the United States based Risley beam steering device. Targeted Improvements: Compared to classical gimbal based beam steering devices, the Risley prism beam steering systems are smaller, use less power and weigh less, making them more immune to vibration and thus able to achieve higher response times and beam steering rates. Description: European alternative for the United States based Risley beam steering device. To design and evaluate a Risley prism beam steering device together with the advantages such a system may provide over a gimbal based device. In particular the expected improvements in response time and pointing error shall be investigated. The activity is divided into the following steps:1) Design of Risley prism based beam steering device for 1064 nm/ 1550nm operation. Perform a beam pointing error analysis taking into account any prism manufacturing tolerances. The design shall be able to withstand the vibration environment encountered during launch and be able to operate under micro-vibration excitation. Establish the steering algorithms.2) Develop and test a Risley prism beam steering device with associated driver electronics and characterise its performance in terms of throughput, field of view and pointing error and to validate the steering algorithms in random step and stare mode.3) Result evaluation and define steps needed to reach EQM. Procurement Policy: C(1) = Activity restricted to non-prime contractors (incl. SMEs).
