Large‐scale additive manufacturing (LSAM) is an additive manufacturing process based on the principles of fused filament fabrication but with significantly higher material deposition rates. The novel hybrid process shown in this paper combines LSAM with a laser beam heat treatment. The structure and mechanical properties of parts are improved due to significantly decreased void sizes. The following article details investigations into the vertical and lateral remelting of strands as well as the utilization of a mirror system, which enables beam guidance according to the machine's printing path.

BR Technologies is enabling a transformer manufacturer to cut its insulation paper in a unique way by using lasers integrated into its machines. The SR 15i CO2laser sources from Luxinar are cutting crepe paper, which is used as an insulation layer inside the electrical transformers that are sold to power grid suppliers.

Iris identification and verification systems have become one of the most accurate biometric modalities due to the iris's unique and distinguishable features. Technical advances have significantly reduced the cost and size of these systems, leading to an increase in the value proposition for several industries. Image resolution and quality of focus are essential in deciphering the complex texture of the iris. Conventional iris recognition devices require bulky and high‐cost systems to overcome the optical constraints of mechanical lens‐based cameras. This paper describes how the use of a liquid lens device can overcome the optical limitations of traditional systems, leading to a low‐cost, smaller, and faster system.

Thickness determination of transparent objects or thick transparent layers can be carried out rather simpy using a chromatic confocal sensor. One obtains the thickness as the difference between two distance peaks multiplied with the refractive index of the object's material. A more detailed analysis however reveals that this result should be corrected by a factor that considers the refraction in detail. In this paper we derive and discuss this correction factor and give tabulated values for different refractive indices and aperture angles of the chromatic probe.

Maintaining image quality when receiving analog and digital video over extended distances has proved to be challenging. Various technology solutions and hardware have been explored and developed to address latency, resolution, and cost issues. This paper will look at these options, and which solutions best address these challenges.
