- W2020894467 abstract "In order to achieve diffraction-limited performance in a distributed aperture optical system such as the multiple mirror telescope, the elements must be optically phased to form a single aperture which can be a difficult task. In this paper, we report a novel, iterative adaptive control method, called far-field optimization, which employs the simplex algorithm to configure the elements of a distributed aperture telescope to optical alignment. Far-field optimization does not require the knowledge of the adaptive mirror surfaces, thus eliminating the need for a wavefront sensor, but uses a simple measure of the point-spread function (image-plane intensity). We present results of computer simulations to demonstrate the utility of far-field optimization to remotely align the six-element multiple mirror telescope in a few seconds, even in the presence of drifting atmospheric turbulence." @default.
