Results closely matched with field-validated manual digitization results, and were significantly faster and less subjective to produce.
By introducing LED blue light in intra- and extraoral cameras, the Cerec system has significantly improved the quality of 3D digitization results.
Huber et al. [ 30] and Goldberg et al. [ 31] have demonstrated that, for SSOCT systems, 8-bit digitization results in only a marginal reduction in image quality and SNR as compared to digitization at higher bit depths.
Solving or at least reclamation, of this problem is possible by preparation of the 3D-digitization result through data filtering, data smoothing and data reduction.
One of the main problems is related with the low quality of 3D-digitization result (noise, measurement errors, redundant data, incomplete data, etc)., which implicates in less accurate surface reconstruction.
For instance, for an 8 bit digital camera, the digitization process results in only 2 gray levels, whereas a 12 bit camera can more accurately represent the real signals using 2 gray levels, provided there are enough photons and the noise is sufficiently low.
Some prospect for this study concerns the observed digitization effect.
Advances in digitization have resulted in "… new ways of acquiring knowledge…and higher rates of innovation" (p. 62).
Cultural heritage documents are often subject to digitization processes resulting in image material, even for textual contents.
The depth sensing range for this system was limited by the amplifier and digitization bandwidths, resulting in an electronic 3dB bandwidth from 17MHz to 500MHz.
The digitization project, the result of two years of scanning using technology developed by NASA, allows users to zoom in on details of the often highly fragmentary scrolls, which contain versions of every book of the Hebrew Bible (except the Book of Esther), including one of the oldest known copies of Genesis and a copy of Psalms containing one of the oldest known references to King David.
