Definitions
- Adjustable bearing arrangement for an object to be accurately positioned relative to a base
- the present invention relates to an adjustable support arrangement for an object to be accurately positioned relative to a base.
- the invention relates to an adjustable storage arrangement for a secondary mirror of a mirror optical telescope.
- Optical reflecting telescopes can be designed and used both for receiving optical radiation (for example: classical telescope telescope) and for transmitting optical radiation (for example: laser active system).
- optical radiation for example: classical telescope telescope
- optical radiation for example: laser active system
- optical reflector telescopes require a structure which, in the region of their aperture, allows suspension of a capture mirror (or secondary mirror) corresponding to the primary mirror (or primary mirror). Both mirrors must be positioned very precisely with respect to each other, so that on the one hand their optical axes are ideally coaxial, on the one hand, and the set one on the other
- Focus distance is as far as possible invariant under all external conditions.
- Telescope structure caused by the required connection carrier between the main and secondary mirrors (primary and secondary mirror) inevitably more or less strong shadowing.
- telescopes such as
- the entire telescope structure would have to co-rotate synchronously, leading to considerable additional problems with regard to achievable directional dynamics (due to the additional inertia about the roll axis), stiffnesses (reduction of rigidity by additional bearings) and accuracies (because of the additional load by Gyros).
- all data and supply lines would have to be connected via rotary feedthroughs or other transformers.
- a full utilization of the main mirror surface would therefore only be achievable by an off-axis arrangement of both mirrors, which leads to significant manufacturing costs of the mirror and the associated feasibility limits.
- Object of the present invention is therefore an adjustable
- Storage arrangement for an object to be positioned precisely relative to a base, in particular for a secondary mirror of a reflecting optical telescope, with which a high-precision positioning of the object can be achieved with little effort.
- This object is achieved by a storage arrangement having the features of claim 1.
- This storage arrangement has at least one support structure connected to the base and the object.
- the support structure in turn has at least two mutually non-parallel struts, each strut is assigned a drivable actuator element such that the actuator element under drive influence the strut with a strut transverse to its longitudinal extent deflecting force applied and wherein the support structure is articulated relative to the base ,
- This construction makes it possible to deflect individual struts by applying a force, for example under the action of a resulting
- the actuator element can be driven by an actuator.
- the actuator element is a driven element of the actuator.
- the support structure has at least four non-parallel struts. As a result, the object in the room is even better positioned, since the inclination and the rotational position of the object can be adjusted by the inventive possibility of changing the air-line distance between the two ends of each strut.
- the storage arrangement preferably has at least two, preferably at least three, more preferably at least four, support structures connected to the base and the object. If each of the support structures is equipped with the adjusting mechanism according to the invention for changing the air-line distance between the two ends of each strut, a multiplicity of
- a particularly effective fine adjustment is achieved in that the struts each have a first, base near end and a second end near the object and that the associated actuator element is arranged so that it is the strut under the influence of drive with the force exerted on the strut force in one of the end regions applied.
- This application of force is not in the Middle section of a strut, but in the end portion, makes it possible to place the drive for the adjustment of the actuator element at the edge of the storage arrangement, whereby this, for example, in the case of use in a telescope, does not contribute to Strahlabschattung.
- the struts each have a band-like shape.
- Such struts have a first width extension, which is many times greater than the second width extension in the direction orthogonal to the first width extension.
- the strut is easily bendable in the direction transverse to the plane of the first, longer width extension, while it is very rigid in the plane of the first, longer width extension.
- This allows a defined bending of the strut in a predetermined direction, namely in a plane which is transverse to the first, longer width extension.
- the visible, clear cross section of the strut, seen in the direction of the second, shorter width extension very small, so that the strut for extending in this direction rays forms only a very small shading surface.
- each strut or a further actuator element which can also be driven by an actuator, is assigned to the strut in such a way that this actuator element is under
- the strut can also be twisted in itself, for example, to minimize the clear cross-section of the strut for running in a given direction rays.
- a torsion of this support structure or of its struts can be effected, which also leads to the clear cross section of the struts for beams extending in a predetermined direction minimize.
- Storage arrangement is used in a telescope of a laser-active system, because then can be minimized by such a minimization of the clear cross section of the individual struts, the strut surface, the laser radiation impinges, whereby both the heating of the struts and the radiation loss can be significantly reduced. Even flat angles of incidence on planes formed by the surfaces of the individual struts can thus be avoided or reduced, which would result in far-reaching and thus particularly harmful scattered light (in contrast to blunt edges or rounded surfaces where the scattered light diverges within the shortest possible distances).
- Connected control device for transmitting control signals so based on the large number of adjustment options of the individual struts complexity of adjusting the position and position of the object can be reliably controlled.
- the storage arrangement is provided with a plurality of supporting structures which form a suspension of a secondary mirror corresponding to a primary mirror, wherein the base connected to the support structures is formed by a reflector telescope housing, wherein the object is formed by a mounting means of the secondary mirror and wherein the secondary mirror is coaxially einjustierbar by means of the actuator elements to the main mirror with respect to the reflector telescope axis.
- This embodiment of the invention is particularly advantageous when the telescope is part of a radiation-emitting laser-active system.
- the invention can also be used on radiation-receiving telescopes, in which case the
- Secondary mirror corresponds to the above-mentioned secondary mirror. It is advantageous if the strip-like struts of the support structures are arranged so that their flat sides in a substantially parallel to Mirror telescope axis aligned plane. In this case, the shading is minimized by the struts for passing through the telescope beams.
- This storage arrangement according to the invention thus provides
- Shading problems are minimized in such a way that: due to the adaptability of the structure, scattered light which arises can always be limited to computable uncritical intensities,

- the anchoring structure 26 has two structural beams 26 ', 26 "spaced from one another in the circumferential direction of the cylindrical support element 13 and extending parallel to the longitudinal axis X' of the cylindrical support element 13.
- the first strut 22 and the second strut 23 are on the first structural beam 26 'in FIG.
- the third strut 24 and the fourth strut 25 are also in the direction of the longitudinal axis X 'of the cylindrical support member 13 from each other
- the four struts 22, 23, 24, 25 radiating in different directions from the cradle 21 form a spatial structure which, together with the structural beams 26 attached to the cylindrical support element 13 ', 26 "and the cradle 21 defines the support structure 20.
- the struts 22, 23, 24, 25 are clamped to the anchoring structure 26, to which end the structural beams 26 ', 26 "have clamping devices.
- the individual struts 22, 23, 24, 25 of a band-like shape that is, that their width extent in a plane parallel to the longitudinal axis X 'of the cylindrical support member 13 is greater than in a direction that parallel to a tangent to the cylindrical support member 13 in the region of the associated structural beam 26 ', 26 "extends.

Due to the initially achievable extremely high

- Fig. 5 The actuators for the force acting on the respective struts a bending force actuator elements, which is referred to in the following functional description, are designated in Fig. 5.
- the deflections caused by the actuators at three bending points per strut always done in the transverse direction. If there is a bending of the strut at the point of action of the actuator, the pretensioned strut must also have two bends at their fixtures; this corresponds to the clamping of a triangle in a flat strut of a not yet deflected support structure. In Fig. 2, these further bending points would be on the anchoring structure 26 as well as on the looping of the bearing pin 21 'through the central portion 21' of the X-shaped strut plate.
- the bending points thus represent one-dimensional solid-state hinges, the axes of rotation of these solid-state hinges at the points of attack of the actuators geometric reasons, however, move spatially by forced running.
- Embodiment illustrated actuators are therefore connected ball-joint to the respective associated strut. Arrangements of rotary joints are also possible at these locations.
- Secondary mirror 16 (arrow Pi in Fig. 6) is described below using the example of a Spider-like arrangement with four guide chains forming support structures shown in FIG. 5 with reference to the schematic representation in Fig. 6.
- Yaw angles are the angles of a pivotal movement of the telescope around the
- Output point of the Roberts handlebar R here is fixed ball-mounted frame-mounted and beyond its kinematic dimensions are to be dimensioned such that including adjustment-related change in the strut lengths his Deflection at point A in (in Fig. 6) corresponds exactly to the amount of the Gangpolverschiebung V vertical direction.
- Rack ring 17 is mounted, and at the other (base) corners respectively the
- Actuators 111 to 114 ball-joint attack are the aforementioned
- the cradles 21 incline in opposite directions to the adjustment angle of the mounting device 15 for the secondary mirror 16. It is clear from the mounting arrangement with four support structures that the two are arranged orthogonally to each other for adjustment angle adjustment
- Support structures must perform a rotational movement about the support point 19 'of the respective cradle 21 about its axis of symmetry in order to avoid a torsion of these struts. From the described degree of freedom of each support structure with ball joint connection to the frame ring 17 also results in the possibility to provide storage arrangements with a theoretically arbitrary number of support structures, such as six support structures of FIG. 4, with simultaneous adjustment movements around the pitch axis and the yaw axis arbitrarily overlay. By analogy, tolerances and possibly resulting asymmetries are automatically compensated for after the adjustment of the storage arrangement has been completed by the individually adjusting pitch and yaw movements of the cradles.
- Secondary mirror 16 takes place on the example of the storage arrangement shown in Fig. 5 with four supporting structures according to the schematic illustration in Fig. 7 in a similar manner.
- the four actuators 111a to 114a of the struts 22a, 23a, 24a, 25a of the right in Fig. 7 support structure 20a synchronously delivered in the arrow direction, wherein on the respective strut acting deflection (bending force) is increased while the actuators 111c to 114c of the struts 22c, 23c, 24c, 25c of the opposite, corresponding
- Support structure 20c are relaxed in opposite directions time synchronously.
- Mounting device 15 for the secondary mirror 16 with respect to the primary mirror 12 along the longitudinal axis X is by delivery
- the spider-like storage concept described allows a sensitive, play and hysteresis-free and at the same time very robust and long-term stable fine adjustment of the support means 15 for the secondary mirror 16 with respect to all six degrees of freedom, which can also be checked and recalibrated at any time.
- Strut alignment angle and phase synchronous with the bandwidth of the controlled beam deflection can be done without causing the intended
- Adjustment state of the storage arrangement changes.
- an optimized strut orientation for realizing minimal shading areas can be realized as follows:
- Support structures can be adapted or by varyingiwer ein too all actuators of the bias state of the entire storage arrangement is controllable.
- Torsion angle of the struts are overcompensated with the same method such that the struts in the range of maximum intensity of the telescopically deflected beams run exactly parallel to these, and that at the same time
- Deviations are greatest where the radiation intensity is lowest. With central irradiation of the struts would correspond to the set
- Torsion angle at the cradle for example, exactly twice the inclination angle of the light beam transverse to this strut. Due to the relatively low
- Mass inertia of the cradles 21 can be made possible by the actuators in conjunction with optimally adapted translation with sufficient strut bias large bandwidths of the adjustment.
- a radial minimum bias of the struts is essential for the adjustability and for the stable use of the bearing arrangement shown, with a further increase in this bias within the load limits of the struts both in terms of robustness against external influences (thermal Expansion, vibration, etc.) as well as in terms of achievable bandwidth with the actuators and external suggestions by upstream positioning systems
- Storage arrangement is advantageous quantitatively detectable by sound spectrum analysis of the individually excited struts.
- Support structure are specifically controlled.
- the invention thus relates to a designed as a telescopic spider storage arrangement, based on a hybrid parallel kinematic, for sensitive, play and
- This telescopic spider is also suitable for the adjustment of off-axis optics, wherein any arrangements of the kinematic structure outside of telescope apertures are conceivable.
- the radiopacity of the spider-like storage arrangement is based on the purpose of avoiding or reducing the scattered radiation on particularly thin strip-like struts whose orientation with each support structure is independent of the JustageSullivan the telescopic spider individually controllable. This will be a
- the described control method for aligning the ribbon-like struts is also suitable for telescopes with integrated high-bandwidth optical beam deflection as described above, with the necessary
- Boundary conditions can be directly derived from the command of the optronic control system and the resulting deflection of the light beam, transformed and phase-synchronized to the command of the actuators of the weighing can be superimposed (according to the chosen target variables for stray light minimization).
- the control of the scattered light minimization is carried out by the same actuators as for the adjustment of the secondary mirror suspension (mounting device 15), wherein the adjustment movements realized for each support structure targeted the "identical
- the storage arrangement is also dynamically adaptable with respect to the support means 15 for the secondary mirror 16 components to be included.
- a very favorable mass-stiffness ratio is determined by kinematic
- the storage arrangement designed as a telescopic spider can theoretically have any desired number of supporting structures (at least two, however), and it acquires increasingly isotropic rigidity properties as the number increases. In addition to the feasibility of maximum directional accelerations, this also creates the possibility of any telescopic swivel angle for complete spherical coverage (rollover capability in the gravitational field of the earth) at the same time
- Both the adjustment of the storage arrangement and the stray light minimization can either, for example by means of a control device, continuously regulated and / or, for example by means of a control device in
- Time intervals are calibrated controlled. If the actuators on the output side have self-locking properties, parking brakes may possibly be omitted (safe state after decommissioning for transport, as well as in case of emergency). If a sensor system for adjusting the telescope structure is integrated with the holder device 15 for the secondary mirror 16, it can be integrated with this
