摘要

Two wave fronts are of interest in the AirBorne Laser, namely, the inbound wave front from the "beacon" and the outbound wave front of the high-energy laser (HEL). Since these two wave fronts propagate through different regions of the atmosphere and at different time instants, the spatial-temporal correlation between the Zernike polynomials' phase expansion coefficients representing these wave fronts must be determined. Using this correlation information, an underlying linear, stochastic, dynamcial system that represents the atmosphere is identified. The wave front sensor and deformable mirror dynamics are also modeled. These models are then used in a Kalman filter which provides estimates of the outbound wave front's Zernike coefficients using measurements of the inbound wave front. A linear quadratic controller is also developed so that conjugation, that is, atmospheric compensation, can be performed. The designed adaptive optics control system's performance is evaluated in a simulated experiment.
