It is conceivable in this context to embody the functional unit of actuators acting at a defined distance with friction fit and/or form fit—for example, based on a toothing—in such a way that a tooth geometry 110 (see in particular
(50) In addition to a limitation of the freedom of movement of the observation unit VU to at least one translation in Z direction or along the optical axis, for example, by a spatial parallel displacement E of the movement axis ZV of the thread 113 relative to the Z axis or optical axis, the support of the pressure plate 23, pretensioned by the spring element 29 with the force FV, via the adjusting unit 28 against a correspondingly embodied stop 114 of the mechanical base 20 is likewise important for compensation of tolerances, vibrations, thermal expansion or the like.

For this purpose, it is provided that in particular at least the inner geometry 126 of the envelope structure 32 is embodied such that the guiding and mounting surfaces 116 to 118 as well as the external shape 127 of the interface element 31 are at least oriented coaxially in the same direction and centered and, in this way, an additional optimization of the rigidity and guiding precision is achieved.

For ensuring a reliable and precise determination of the adjusting range, it is also conceivable when determining the end stops to additionally take into account the at least sensor-based measured brightness value, for example, from the image recording unit 15 or 15′, in such a way that in the simplest case end stops can be determined by the minimum (first occurring adjusting position without impinging light or sensor measurement) and the maximum (first occurring adjusting position with maximum brightness) of the brightness value. An exact correlation of f-stop or mechanical adjusting position for aperture can thus be precisely computed or interpolated by use of the respective known aperture range. In addition to an advantageous manual adjustment of an exact aperture value, in combination with an automatic control of the electronic image parameters, a precise automatic control of substantially arbitrary lenses in general and at least of the aperture in particular can be achieved.

As a result of the system-inherent flexible scaling, by means of an at least geometric enlargement as well as reduction of the whole system the minimally and maximally achievable distance of the individual synchronized (camera) systems can be reduced or enlarged likewise.

(108) Even though the external system geometry in general has been illustrated and described above as a cylindrical shape, it is understood that likewise other substantially freely selectable external geometries are conceivable. An adaptation to arbitrary structures can be enabled in this way and the whole system can be achieved for installation in further functional units, modules or systems, as shown is in exemplary fashion in
(109) For this purpose, it is provided that the holding geometry WD, in analogy to the combination with an interface element 31 according to
(110) In addition to the movement generation on the basis of an (electro)magnetic or piezoelectric principle, further actors—for example, fluid-driven or compressed air-driven and conventional (wave) or gear-based (step) motors—are conceivable as well as an expansion of substantially arbitrary functional units for movement generation with corresponding electronic and/or mechanical functional units (e.g., encoders) for exact reproduction of adjusting movements and/or for the safe movement into discrete (stored) positions and orientations. In addition, it is conceivable that by means of reference sensors—for example, by means of additional sensor XS (
(111) It is understood that, for configuration of a pretensioned mechanical system, in addition to the described embodiments, alternative spring elements such as, for example, spiral springs, wave springs, plate springs, flexure springs or pretension-inducing functional units that are water-, air-, and oil pressure-activated or the like—as well as support elements—for example, rolling bearings, magnetic bearings, flexure bearings or similar bearings—are conceivable.
(112) Moreover, it is in particular conceivable to respectively embody the (rotatory) signals lines, of the whole system to the exterior and as an alternative to the described internal transmission by means of the described component SR (
(113) It is also understood that a system structure that is completely protected against external influences and media can be achieved elastomer-based or polymer-based as well as by metallic sealing surfaces. Corresponding sealing elements can be embodied in this context also in a multi-part configuration. Moreover, e.g., for weight reduction, it is conceivable that the whole system, at least in sections thereof, is embodied without sealing elements and the mechanical structure for this purpose is provided as a rigid unit which surrounds at least partially the inwardly positioned modules and functional elements. In particular, in this context the external structure, for example, can make accessible the control members of a connected lens by correspondingly designed openings and, in this way, enable a manual operation thereof as well as ensure protection of the surrounding functional elements and modules from external influences and accidental displacement.
