Neural network controller for Tunable Liquid Crystal Photonic Device work as Laser Beam Steering Device

In this paper, artificial neural network controller (NNC) was designed and used to adjust and control the work of the laser beam steering device consist of liquid crystals cell and other optical components. The target of the neurocontroller is to guarantee smooth deliver and exactly control the laser beam to a required location via control the liquid crystals cell and the optical components. Back propagation method is used to build up the neurocontroller, main artificial neurocontroller software is consists of three sub programs according to the three functions it proposed to administer. Trial results obtained after the execution of the neurocontroller affirmed the optimum performs in administrating, controlling and standardize the device while the value of the errors reached its minima, which coincidence with the approaches of the paper goals.
