Textured laser range scanning and registration of the cortical surface
A novel method for intra-operative data acquisition using a laser range scanner is presented for applications in model-updated image-guided surgery. The scanner produces a point cloud containing true-color encoded range data of its field-of-view. This allows characterization of intra-operative conditions using both intensity and geometry information. Furthermore, a rigid-body registration algor...
متن کاملThe influence of laser-textured dentinal surface on bond strength.
OBJECTIVE To assess the influence of laser-textured surfaces on the adhesion of composite to dentin after being rotary prepared. METHODS Thirty healthy teeth were kept in 0.1% thymol solution prior to being ground down to dentin to create a 4 × 4 mm² flat surface. Teeth were divided into 3 groups (n=10). Groups 1 and 2 utilized the prototype Erbium doped, Yttrium-Aluminum-Garnet Er:YAG laser ...
متن کامل3D Textured Surface Modeling
Because object geometry varies at many scales, it is often convenient to distinguish shape from texture. While shape is a deterministic macroscopic description, texture is a finer scale geometric description with some repetitive or random component. The distinction between texture and shape is important when developing object recognition systems. Acquiring fine scale geometry is difficult due t...
متن کاملGraphene-Ag Hybrids on Laser-Textured Si Surface for SERS Detection
Surface-enhanced Raman scattering (SERS) has been extensively investigated as an effective approach for trace species detection. Silver nanostructures are high-sensitivity SERS substrates in common use, but their poor chemical stability impedes practical applications. Herein, a stable and sensitive SERS substrate based on the hybrid structures of graphene/silver film/laser-textured Si (G/Ag/LTS...
متن کاملLaser Textured Surfaces for Mixed Lubrication: Influence of Aspect Ratio, Textured Area and Dimple Arrangement
Unidirectional sliding experiments with polished and laser textured steel surfaces were carried out to investigate the effects of different textured area densities, aspect ratios and dimple arrangements. The system was lubricated with Polyalphaolefin (PAO) at 100 °C and the contact pressure was 3 MPa. For measuring Stribeck curves, the sliding speed was controlled between 40 and 2000 mm/s. The ...
