  • 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
  • Specs to Know for Imaging Lenses
    of view, resolution, working distance and depth of field. When specifying a machine vision system, many engineers think in terms of magnification. Magnification however is a relative specification and depends on the size of the image sensor and display device. For example, 50X magnification can
  • Fundamental Parameters of an Imaging System
    Field of View (FOV): The viewable area of the object under inspection. In other words, this is the portion of the object that fills the camera's sensor. Depth of Field (DOF): The maximum object depth that can be maintained entirely in focus. DOF is also the amount of object movement (in and out
  • 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
  • Off-The-Shelf Integration
    lens mounts, achromats, red dichroic filter, C-Mount iris, monochromatic camera, line generator laser, capture board and software. The depth of field requirements are unknown. For this reason, the lens should incorporate a manual iris. The object resolution needed is also uncertain; providing

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

  • Image-Based Rendering
    When the geometry is represented as a depth field on the reference camera, forward mapping can be performed quickly with simple pixel offset and scanline-based splatting as described earlier.

  • 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.

  • 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.
