A new method of generating of a Structured Laser Beam (SLB) has been proposed recently. The SLB is a pseudo-non-diffractive optical beam. Its transverse optical intensity profile looks similar to that of a quasi Bessel beam and shows a narrow central core of high intensity surrounded by concentric circles. The SLB has the ability to propagate over very long distances, theoretically to infinity...
Hexagon has recently presented a new generation of Leica Absolute Laser Trackers to the market.
During development Absolute Laser Trackers are exposed to a very comprehensive suite of environmental tests, following normed testing standards as well as special/ adapted tests exposing the systems to stress conditions customers expect it to operate in.
In this paper we will present the results...
This article summarizes part of the research related to the properties of the structured laser beam (SLB). The SLB has the potential to be used as a long reference line for alignment applications. This is due to SLB features such as a very clear spot in the center of the beam, a sharp demarcation of the central spot, low divergence of the central spot (practically measured value 10 μrad),...
