    摘要： In illustrative modes of practice, heliostat devices integrate light reflecting panels with a composite supporting structure that helps to provide the resultant assembly with structural integrity and stiffness. Light reflecting panels are coupled to the supporting, composite structure by a plurality of flexible connecting elements. Advantageously, the composite approach of the present invention effectively separates structural and thermal compensation functions. Specifically, the composite support structure helps to provide desired structural properties. In the meantime, the flexible connecting elements couple the top, light reflecting panel to the support structure in a manner that helps to isolate the top, light reflecting panel from thermal stresses that otherwise could cause undue slope errors.

    摘要： The invention relates to a method for compensating aberrations of an active optical system by a deformable mirror (1), comprising:
    (a) formation of a matrix N, binding the optical system aberrations with the displacements of the surface of a deformable mirror (1), presented as a superposition of natural frequency modes of a mirror simulator (3) having the same geometric shape and the same elasticity characteristics as the deformable mirror (1) but having zero density except for concentrated masses attached at points corresponding to the places of action of force actuators (4) onto the deformable mirror (1);
    (b) formation of a matrix M, binding the coefficients of the natural frequency modes of the mirror simulator (3) with the forces or displacements of the force actuators (4) that deform the mirror (1);
    (c) generation of a matrix F of forces or displacements for loading the deformable mirror (1) on the basis of the aberration measurement, using the matrices N and M.

    摘要： The object of the invention is a sandwich-type facet having high rigidity, designed such that variations in the optical quality and curvature thereof, due to the influence of the working conditions, are minimized with respect to other known facets. The facet of the invention is preferably formed by two outer mirror layers, attached by polymer foam having a specific formulation and design, which is deposited in cream phase on one of said mirror layers. More preferably, the design of the geometry of the different layers is configured such that equilibrium is obtained between the internal stresses and deformations of the facet, generated by temperature deviations from the working conditions, and particularly the thermal gradient existing between the faces in working conditions, thereby maximizing the mechanical inertia of the facet for the purpose of improving the rigidity thereof.
