摘要： The deformable optical system comprises at least one optical element (10), an actuator facility (20) and a control unit (30). Therein the at least one optical element (10) has a body (12) with a thermal expansion coefficient and the actuator facility (20) serves to exert a force distribution at a main surface (16) of the body (12). The control unit (30) is arranged for controlling the actuator facility (20) in order to control a shape of the body (12). The actuator facility comprises a body layer (22) formed on said main surface (16) of the body (12) and the body layer has a thermal expansion coefficient differing from the thermal expansion coefficient of the body. The actuator facility further comprises a thermal array (24) facing the body layer (22) and distanced from said body layer (22) by a gap (26). The thermal array has a plurality of thermal elements (250, T i , T 1 ,...T 5 ) distributed at a surface of the thermal array facing the body layer that allow for a heat flow between the thermal array and the body layer. The heat flow has an amplitude controlled by the control unit (30) as a function of the position on the thermal array and as a function of time.

摘要： A method and system for maintaining an optimized point ahead angle (Θa) between an uplink beam (U0) from a first terminal (10) to a second terminal (20), and a downlink beam (D0) from the second terminal (20) to the first terminal (10). While transmitting data via a transmission channel (Tx) from the first terminal (10) to the second terminal (20), a directional variation (ΔΘ) is applied to an initial point ahead angle (Θ0) for emitting the uplink beam (U1,U2) along different point ahead angles (Θ1,Θ2). A respective intensity (I1,I2) is determined of a part of the uplink beam (U1,U2), received by the second terminal (20), emitted by the first terminal (10) along a respective point ahead angle (Θ1, Θ2). The initial point ahead angle (Θ0) is adjusted towards an optimized point ahead angle (Θa) based on the respective intensity (I1,I2) as function of the different point ahead angles (Θ1,Θ2).
