  • Patent number: 11906284
    Abstract: A method for detecting an edge of an object is carried out by means of a detection device (10), which has an emission region running along a first straight line and has a receiving region which runs along a second straight line, which is arranged in parallel to the first straight line. An emission subregion (11a-p) of the emission region is selected, which extends up to a first end of the emission region. Light is emitted from the emission subregion (11a-p) and a light signal of light reflected on the object is received in the receiving region. The emission subregion (11a-p) is then shifted along the first straight line in the direction of a second end of the emission region. Emitting, receiving and shifting are repeated until the emission subregion (11a-p) extends up to the second end at the start of the shifting step. A signal course is compiled from the received light signals, and the detection of the edge from the signal course is carried out.

  • Patent number: 11906286
    Abstract: The invention discloses a deep learning-based temporal phase unwrapping method for fringe projection profilometry. First, four sets of three-step phase-shifting fringe patterns with different frequencies (including 1, 8, 32, and 64) are projected to the tested objects. The three-step phase-shifting fringe images acquired by the camera are processed to obtain the wrapped phase map using a three-step phase-shifting algorithm. Then, a multi-frequency temporal phase unwrapping (MF-TPU) algorithm is used to unwrap the wrapped phase map to obtain a fringe order map of the high-frequency phase with 64 periods. A residual convolutional neural network is built, and its input data are set to be the wrapped phase maps with frequencies of 1 and 64, and the output data are set to be the fringe order map of the high-frequency phase with 64 periods. Finally, the training dataset and the validation dataset are built to train and validate the network.

The support arm has at least one mount, which is concentric with the axis of rotation, for the spring element, which, when arranged on the mount, is bent at least in part around the axis of rotation. As a consequence, centrifugal forces that act on the spring element when the rotating head is in operation have no influence on the tension of the spring element.

  • Patent number: 11906301
    Abstract: A thickness evaluation method of the cell sheet according to the invention includes tomographically imaging a cell sheet by optical coherence tomography and obtaining a thickness distribution of the cell sheet based on a result of the tomography imaging. A tomographic image corresponding to one cross section of the cell sheet is obtained by tomography imaging while scanning the light in a main scanning direction. The tomography imaging is performed in every time while moving an incident position of the light at a predetermined feed pitch in a sub-scanning direction, thereby a plurality of the tomographic images corresponding to a plurality of cross-sections are obtained. One-dimensional thickness distributions of the cell sheet in the corresponding cross-sections are obtained based on each of the plurality of tomographic images, and a two-dimensional thickness distribution of the cell sheet is obtained by interpolating the one-dimensional thickness distributions.
