A still further problem encountered when transmission disk spinners are used as the scanning element is the influence of spinner "wedge" on scanner performance. Variations in the thickness of the substrate material, which can occur in the form of localized deviations or of a constant wedge, cause...
37, for each mechanical configuration of the calibration equipment 16, 177, and 226 (e.g. physical position or optical magnification setting), the calibration method is as follows: At step 241, a virtual calibration pattern is projected in the field of view of a desired object. At step 242...
3.1. Preparation and Characteristics of the Pellets In Table 1, the pellet codes, the composition of solids in the pellets, and the volume of liquid binder required per 20 g solids to form spherical pellets with the narrowest size distribution are shown together with the corresponding “apparent...
According to Equation (10), when the half field of view increases, in order to keep the detection ability of the system unchanged, we can only reduce the lateral magnification to improve the illumination. Barrel distortion is the kind of aberration that compresses the edge of the image plane...
