Two-Axial Measurement of the Angular Microdeflection of a Laser Beam Using One Single-Axis Sensor

open access: yesSensors, 2023
The majority of current methods for measuring the angular deflection of a laser beam enable measurement only in one selected plane. However, there are tasks in which measurements of laser beam deflections in 3D are required.

MEASUREMENT OF DEFLECTION LINE ON BRIDGES [PDF]

open access: yesReports on Geodesy and Geoinformatics, 2013
Abstract Prestressed concrete bridges are very sensitive to the increase in long-term deflections. Reliable forecasts of deflections of bridge structures during construction and durability are crucial for achieving good durability. The main results of measurements are the changes of the deflection line of the bridge structures, which places ...
