  • Gauging Depth of Field in Your Imaging System
    Over the years, we have answered countless questions regarding lens performance. Of those questions, none have been more difficult to define than requests for depth of field. The reason for this difficulty has more to do with the vagueness of the question than with the inability to provide
  • Thermal FEA keeps football field green in Winter
    Engineers used heat-transfer capabilities in an FEA program to find the right depth and shape of a heating system that will warm the grass of a football field. The right amount of heat can keep the grass growing and healthy during the cold playing season. The turf-conditioning system has 11.65
  • 3D Visualization for Industrial Quality Inspection
    Vertical resolution in the balance between. numerical aperture and depth of field. Surface. analyses, fracture analyses, analyses of inclined or vertical surfaces or onsite inspections of large parts such as turbine. rotors are just a few examples in which the strengths of digital microscopes make
  • Invitation to the SEM World
    Microscope (SEM) covers a wide range of magnification, about x 10 to x 1,000,000. The figure below, "(SEM Magnification)" indicates an appropriate SEM magnification for observing each object. Some of the SEM's most important features are easy magnification changing over, large depth of field (depth
  • Medical Device Link .
    is acquired becomes the principal factor limiting throughput of slide-digitizing and HTS systems. An optical technology that increases the depth of field of microscope imaging systems also increases the speed and efficiency of automated slide-screening and discovery applications. This technology, called
  • Tight Squeeze: Optical Imaging For Cramped Quarters
    A six-step strategy helps fit imaging systems onto semiconductor equipment where space is at a premium. Fundamental parameters of an imaging system include the depth of field, field of view, resolution, working distance, and sensor size. A magnification of one means the imaged area equals
  • Shedding light on vision systems
    Before setting up a vision system, understand the basic parameters involved. The fundamental parameters of imaging systems include the resolution of the object, the field of view, and the depth of field. The working distance from the object to the lens is also important, as is sensor size. Primary
  • Choosing the Correct Testing Target
    characterize image quality in terms of its components: resolution, contrast, depth of field, and distortion. The ability of a lens to maintain a desired amount of image quality as the object moves in and out from best focus. DOF should be defined with an associated resolution and contrast

  • An intensity-based cooperative bidirectional stereo matching with simultaneous detection of discontinuities and occlusions
    Based on a new model of piecewise smooth depth fields and the consistency constraint, the algorithm is able to estimate the 3-D structure and detect its discontinuities and the occlusion reliably with low computational costs.
  • Encyclopedia of Solid Earth Geophysics
    The temperature- depth field for the Cordillera, therefore, is much hotter than for a cratonic region (Figure 4a).
  • Optical Imaging and Spectroscopy
    As with the canonical wave and correlation field multiplex systems presented in Sections 10.2 and 6.4.2, coded aperture imaging provides a very high depth field image but also suffers from the same SNR deterioration in proportion to source complexity.
