  Image Processing Sensor
  ... The advantage of telecentrics is that the lateral magnification remains constant when the working distance is altered ... This is especially important when working with lower magnifications. The best quality can be attained using telecentric lenses with a fixed magnification. From an applications standpoint, it makes sense to combine high and low

  Principle of X-ray Tomography
  ... a flat sensor – images are taken for various rotated positions; b) Magnification adjustment: movement of the measured object relative to the sensor ... to measurement using image processing, it is possible to change the magnification using tomography (Fig. 35b) in order to capture small parts with higher

  Multisensor Coordinate Measuring Machines with X-r...
  ... and guide components come from the family of coordinate measuring machines described above. Using this construction, calibration data such as magnification, rotary axis position and geometric corrections are stable over long periods. Fig. 37: Design of a multisensor coordinate measuring machine with components for X-ray tomography. The basic machine construction is shown in Figure 37. The linear axes serve to adjust the

  Visual Sensors
  ... with a reticle, a final resolution of several microns can be attained by using this technique, for example, in conjunction with a 100 × optical magnification. Fig. 7: “I still can’t see anything.” (Cartoon by Manfred Pühn)

  Specification and Acceptance Test
  ... nonlinearities or hysteresis on reversal in the probe. For optical sensors, these factors include the resolution of the sensors, the optical magnification of the lens systems, the depth of field when measuring with the autofocus and, with laser sensors, the radiant reflectance of the material ... that a sensor calibration error (caused by, for example, incorrect probe sphere diameter, incorrect origin of laser coordinates, or incorrect

  ... aperture reduces the depth of field and increases the precision of the measurement taken with the autofocus. With conventional lenses, high magnifications yield the best results. The chief disadvantage of the technique described above is that a certain range must be traversed along the optical ...
