Risley prisms are commonly used in continuous scanning manner. Each prism is capable of rotating separately about a
common axis at different speeds. Scanning patterns are determined by the ratios of the wedge angles, the speed and
direction of rotation of both prisms. The use of this system is conceptually simple. However, mechanical action in most
applications becomes a challenge often solved by the design of complex control algorithms. We propose an electronic
servomotor system that controls incremental and continuous rotations of the prisms wedges by means of an auto-tuning
PID control using a Adaline Neural Network Algorithm, NNA.
