Surface Profile Determination from Multiple Sonar Data Using Morphological Processing
This paper presents a novel method for surface profile determination using multiple sensors. Our approach is based on morphological processing techniques to fuse the range data from multiple sensor returns in a manner that directly reveals the target surface profile. The method has the intrinsic ability of suppressing spurious readings due to noise, crosstalk, and higher-order reflections, as w...
متن کاملComparative Surface Roughness Evaluation of a Novel Aesthetic Restorative Material using Profilometer - An In Vitro Study
Aim: To evaluate and compare the surface roughness of nano ionomer, microhybrid composite, and resin modified glass ionomer cement. Method: A total of 30 PVC moulds of dimension (diameter 8mm height 2mm) were prepared. The total of 30 specimens was divided into three groups each consisting of 10 discs each. Group110 discs made of microhybrid composite (Z250, 3M ESPE, St. Paul, MN, USA), Group 2...
متن کاملA 3D Optical Surface Profilometer Using a Dual-Frequency Liquid Crystal-Based Dynamic Fringe Pattern Generator
We propose a liquid crystal (LC)-based 3D optical surface profilometer that can utilize multiple fringe patterns to extract an enhanced 3D surface depth profile. To avoid the optical phase ambiguity and enhance the 3D depth extraction, 16 interference patterns were generated by the LC-based dynamic fringe pattern generator (DFPG) using four-step phase shifting and four-step spatial frequency va...
متن کاملNovel reflected light confocal profilometer
We present an instrument that uses a novel technique to render topographical maps of microscopic reflecting surfaces in which depth resolution can be an order or magnitude or more better than the lateral resolution of the confocal microscope. In a confocal scanning reflected-light microscope, the illumination light coming out of the objective is a cone of light with its axis parallel to the opt...
متن کاملProfile characteristics of cut tooth surfaces developed by rotating instruments.
THE irregularity of the cut tooth surfaces resulting from the shaping of cavities would appear to have a twofold significance. First, these irregularies should have some effect on the adaptation of the specified filling material to the cavity walls, and second, they may tend to undermine or weaken groups of enamel rods at the eavo-surface margins, thus resulting in a failure of the tooth struct...
