A Study on the Uncertainty of a Laser Triangulator Considering System Covariances
Sensors, 2020 A laser triangulation system, which is composed of a camera and a laser, calculates distances between objects intersected by the laser plane. Even though there are commercial triangulation systems, developing a new system allows the design to be adapted ...

Advanced Science, EarlyView.A monolithic manufacturing strategy is presented for photothermal shape memory alloy (SMA) meta‐morphing structures. Using a single‐step UV‐laser process, the mechanical compliance is programmed via kirigami patterning while optical absorbance is simultaneously tuned through surface oxidation.

Long range laser traversing system [PDF]
, 1974 The relative azimuth bearing between first and second spaced terrestrial points which may be obscured from each other by intervening terrain is measured by placing at one of the points a laser source for projecting a collimated beam upwardly in the ...

Coaxial laser triangulation for height monitoring in laser metal deposition
Procedia CIRP, 2018 Abstract The control of the height parameter plays a crucial role in the laser metal deposition (LMD) process. A mismatch between the deposition height increment and the process growth rate can generate geometrical inaccuracies as well as collisions. The paper presents a method based on triangulation for monitoring in-line the height on a LMD system ...
