چکیده
I MOIRE PATrERNS AND TWO· DIMENSIONAL ALIASING IN LINE SCANNER DATA ACQUISITION SYSTEMS C. D. McGillem T. E. Riemer I The basic mechanism underlying the generation of Moire patterns in line scanner data acquisition systems is examined. A general expression 1s developed in terms of typical system parameters for the reproduced image of such systems and the interaction of the image spectrum; the raster frequency and digital sampling frequency of the AID conversion process are discussed and examples given. System design requirements , for avoiding Moire pattern generation and two-dimensional aliasing are discussed.

A Sampled-Grating Model of Moire Patterns from Digital Imaging
Traditional “crossed-grating” moire, as well as newer ”sampled-grating” (scanning) moire. have proven to be effective methods of shape measurement. There is speculation that the moire patterns of a sampled gating, which are due to aliasing, can be modeled with crossed gratings. We compare the two and show that while crossed gratings can correctly predict the frequencies of a sampled grating, th...
متن کاملImage resampling between orthogonal and hexagonal lattices
Resampling techniques are commonly required in digital image processing systems. Many times the classical interpolation functions are used, i.e., nearest-neighbour interpolation and bilinear interpolation, which are prone to the introduction of undesirable artifacts due to aliasing such as moire patterns. This paper presents a novel approach which minimizes the loss of information, in a least-s...

متن کاملOcclusion Area as Suitable Guidance for Terrestrial Laser Scanner Localization
Terrestrial Laser Scanner (TLS) technology, have altered quickly data acquisition for map production in surveying. In many cases, it is impossible to complete surveying of the desired area without TLS displacement in one station to another. Occlusion is innate in data acquisition, with this type of device. To solve this problem, TLS devices should be placed in different locations and scanning o...
متن کاملDevelopment of a new laser-line and CCD based optical-CT scanner for the readout of 3D radiation dosimeters
We present initial results on the comparison of the dose readout from a three dimensional polymer gel dosimeter using two different optical-CT systems; i) a common wide field and a wide area detector optical-CT system and ii) a new ‘laser-line’ and wide area detector based optical-CT system. The findings presented herein highlight the advantage of the laser based over the wide field optical-CT ...
