A method for determining the registration of an adaptive optical system is presented. Three deformable mirror actuators are sinusoidally driven at a high rate and the resulting gradients are measured using a Hartmann sensor. The gradient measurements are used to determine the translational, rotational, and magnificational registration of the deform...

... misregistration has three parameters: the rotation, θ, and the center of rotation, denoted by x θ and y θ . Rotational misregistration is illustrated in figure 3. The nominal coordinates of the center actuator (or center subaperture corner) are indicated as well as the perturbed locations of the center subaperture corner. ...

This work deals with an analysis of an influence of the third-order aberration design of an optical system for a specific position of the object on the diameter of the circle of confusion, the centroid of the spot diagram, and the position of the optimum image. Explicit analytical formulas are derived for the calculation of fundamental third-order...
