20100170925 | ACCESSORY HOLDER FOR HANDLEBARS - An accessory-holding assembly is provided for holding portable accessories on a set of handlebars. The assembly includes an elongate member sized to receive two or more general-purpose clips often associated with portable accessories. The elongate member may be part of an accessory holder that can be removed, with the accessories still attached, from the handlebars. This allows a rider to remove a plurality of portable accessories from the handlebars in a single action so that the rider can carry the entire accessory holder, including the accessories, into an area where bicycles are not permitted (e.g., an office). The elongate bar may also be attached to a bracket at its two ends to define a space therebetween so that part of each general purpose clip can be inserted into the space. If the space has proper dimensions, the clip is not likely to fall out while the rider is riding. | 07-08-2010 |

20090021750 | Method and Arrangement for a Rapid and Robust Chromatic Confocal 3D Measurement Technique - The invention relates to a chromatic confocal technique method and arrangement for the rapid three-dimensional measurement, in particular, of object shape, more particularly of a tooth in the jaw of a human being with an array of polychromatic point light sources, a planar detector matrix, arranged before means for lateral spectral separation and an objective for object illuminating and recording. According to the invention, spectral defined reference light bundles are generated also using components of the arrays of point light sources for chromatic calibration, wherein said reference light bundles are injected into the detection beam path via a reference bean path for chromatic lateral separation and then focused on the detector matrix as reference image points. Spectral reference points are calculated at the detector matrix positions and sub-matrices for spectral analysis of object light are digitally stored with pixel accuracy by means of the above positions which then serve for obtaining measurement points such that the detector matrix may be completely filled out with oblong sub-matrices, the planar array is arranged on the planar detector matrix rotated about an acute angle to the spectral axis, wherein the rotation is carried out about the optical axis (OA) of the arrangement, such that a connecting line of point light sources on projection thereof in the plane of the detector matrix includes an acute angle there with the spectral axis, the λ-axis. | 01-22-2009 |
20110235045 | METHOD AND APPARATUS FOR INTERFEROMETRY - A method and an arrangement are provided for scalable confocal interferometry for distance measurement, for 3-D detection of an object, for OC tomography with an object imaging interferometer and at least one light source. The interferometer has an optical path difference not equal to zero at each optically detected object element. Thus, the maxima of a sinusoidal frequency wavelet, associated with each detected object element, each have a frequency difference Δf_Objekt. At least one spectrally integrally detecting, rastered detector is arranged to record the object. The light source preferably has a frequency comb, and the frequency comb differences Δf_Quelle are changed in a predefined manner over time in a scan during measuring. In the process, the frequency differences Δf_Quelle are made equal to the frequency difference Δf_Objekt or equal to an integer multiple of the frequency differences Δf_Objekt at least once for each object element. | 09-29-2011 |

20120307258 | METHOD AND ARRANGEMENT FOR ROBUST INTERFEROMETRY - An arrangement and a method are provided for robust interferometry for detecting distance, depth, profile, form, undulation, flatness deviation and/or roughness or the optical path length in or on technical or biological objects, including in layered form, or else for optical coherence tomography (OCT), with a source of electromagnetic radiation and with an interferometer, in particular also in the form of an interference microscope, having an object beam path and having a reference beam path, in which an end reflector is arranged, and a line-scan detector for detecting electromagnetic radiation in the form of at least one spatial interferogram. | 12-06-2012 |
20140022553 | Method and Arrangement for Short Coherence Holography - The invention relates to a method and arrangement for short coherence holography for distance measurement, for profile detection and/or for 3D detection of one or more object elements and/or object areas and/or objects or for readout of holographic volume memories with a holographic interferometer and with at least one short coherence light source. For each optically detected object element in the hologram the holographic interferometer has an optical path difference clearly unequal to zero. At least one spectrally integrally detecting, rastered detector is arranged. The short coherence light source with frequency comb is designed with the optical delay length Y1. Detected holograms are digitally reconstructed. Relative distances of object elements are digitally calculated from the hologram reconstructions, so that a 3D point cloud of object elements and/or object areas and/or objects is produced. Data can be read out optically in parallelised form from holographic volume memories or three-dimensionally structured signatures. | 01-23-2014 |
