Abstract

In most applications of laser technology and optics the beam quality, the ability to focus a laser beam and the achievement of a good optical resolution play an important role. For the compensation of distortions adaptive optics is used. Classical adaptive-optics control schemes use matrix operations, which show a non-linear computation time dependence with matrix size, making it difficult to achieve high control loop frequencies at high resolution. A novel closed-loop adaptive optics is presented using a massively-parallel neural network in an all-hardware setup. It can be used for a fast real-time wave front sensor and for closed-loop operation.
