Correlating Displacement Sensors and In-Situ Optical Imaging for the Layer Management in a Laser Powder Bed Fusion Process

Sabarad, Satvik IrappaMassachusetts Institute of Technology2022

… is repeatable across different setups. The laser triangulation sensor was used to correlate with the camera images. The second method, (Convolutional Neural Network (CNN) based machine learning model), classified the images with 94% accuracy. Both of these methods were deployed on the …

A three dimensional vision system for industrial surface topography measurement

Reynolds, Matthew C.Thames Polytechnic1990

… is concerned with a research programme into a triangulation based Surface Topography Measurement (STM) system. The particular system investigated produces a series of three dimensional coordinates of points on a target surface which has been placed in front of the STM system. It is designed for …

Modeling and Experimental Validation of Disc and Reed Style Check Valves for Hydraulic Applications

Knutson, Anthony2016

… check valve position during operation using a laser triangulation sensor (LTS) was developed. An acrylic viewing window was installed in the check valve manifold to allow optical access. To precisely measure position through air, acrylic, and oil, refraction of the laser light was accounted for …

Effects of controlled vibration induced gapping on the torque performance of lubricated ball bearings

Sochting, SvenUniversity of Central Lancashire2003

… bearing ring displacements by means of two laser triangulation transducers as well as a apparatus to measure the resulting impact on the bearing torque behaviour. The investigation was performed on hard-preloaded SEA 65 type bearing pairs, which were lubricated with both; Braycote 601 EF …
