Disclosed is a distance meter, particularly for telescope arrays in ground-based or space-based applications for detecting surfaces. Said distance meter comprises at least one radiation source for emitting electromagnetic radiation (ES) onto a target that is to be measured, a receiver unit with a sensor (11) for receiving the radiation (S) reflected by the target and deriving distance data, and a first spectral filter component (4) According to the invention, the angular spread of reception of the reflected radiation (S) is limited by means of at least one spatial filter component (6′), especially a fiber laser as a radiation source and receiver component.

The invention relates to an optical inclinometer. According to the invention, an incline-dependent medium, e.g. a liquid surface, is positioned in the pupil of an optical subsystem and a detectable wave front is imaged onto a detector by means of said medium. A phase displacement of radiation emitted from a radiation source is caused by said medium; the interaction of the radiation and the medium can take place during reflection or transmission. An aberration of the wave front caused by the medium can be analyzed by means of a wave front sensor and compensated by an evaluation unit or the detector. A wave front sensor having a diffractive structure formed upstream of each subaperture is compact and increases the resolution and the detectable angular region of the inclinometer.

The invention relates to a method for high-precision fixing of a miniaturized component (1), in particular having a microoptical element (2), on a predetermined fixing section (3) of a support plate (4) by a solder joint. The support plate is formed throughout from a metallic material and has a cut-out region (10) which encloses the fixing section (3), is bridged by at least one connecting web (9) of the support plate (4), keeps the heat transfer from the fixing section (3) to the remaining support plate low and compensates lateral thermal expansions of the fixing section (3). Solder material (8) is applied on the top of the fixing section (3). The method comprises in particular the steps: arrangement of the component (1) above the fixing section (3), the solder material (8) and the base (7) of the component (1) being present in opposite positions without contact and forming a space. Supply of electromagnetic radiation (12) to the bottom (6) of the fixing section (3) for melting the solder material (8′) so that, as a result of drop formation and optionally as a result of lowering of the component (1) the space fills with molten solder material (8′) for mutual fixing. Waiting for the mutual fixing by resolidification of the molten solder material (8′).

An application controller for an application unit, for marking substances comprises a radiation sensor, by means of which the relative position of the application unit relative to a reference plane may be determined. The relative position of the application unit can be determined by means for recording the orientation of the application unit controller relative to the reference plane from the association of position with orientation information, such that control instructions, in particular for positional correction may be generated by the application unit controller. The position of the application unit can be adjusted by an actuator device according to the control instructions.

A force measuring device comprises at least one gauge element which, at least, in some regions, is conceived as a spring element, the deformation of which changes the volume of liquid contained in a chamber delimited by the gauge element; the spring elements are equal to each other in every respect and so positioned that the spring characteristic is the same for all of them that the deformation remains in the linear domain of the spring characteristic and that the local change of volume of the chamber is proportional to the deformation of the respective spring element.

摘要:
A target plate (Z) according to the invention for positioning components, in particular pipes (R1, R2), has a holographic optical element as a holographic diffusor. By means of the diffusor, radiation striking the target plate (Z) in the form of a reference beam (RS) can be guided very accurately and virtually without loss into a defined solid angle region (dΩ). Furthermore, the diffusor may have stochastically distributed structures and thus illuminate the solid angle region (dΩ) homogeneously. By means of the target plate (Z), the visibility of the incident reference beam (RS) is increased, and the reference beam (RS) can also be detected independently of position.
