  • Understanding Laser Classifications and Output Levels

    Mainstream, low-powered lasers that emit continuous wave beams are harmless to humans. However, there are some lasers that can cause serious damage to one’s skin and eyes. To educate and protect people from using such lasers incorrectly – in a way that could cause injury – regulatory institutions have created a classification system that establishes the level of damage that the ...

  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

    Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...

  • Distribution of mean flow and turbulence statistics in plunge pools

    When the capacity of the spillway of a dam is exceeded for a given flood, overtopping occurs; in such cases potentially dangerous hydrodynamic actions and scour downstream of the dam need to be foreseen. Detailed studies of jets impinging in plunge pools from overflow nappe flows are scarce. This work addresses plunge pool flows, and compares numerical results against our own experiments. The ...

  • REVO-2 and the ATOM encoder - Case Study

    The REVO multi-sensor system is one of Renishaw's flagship products and enables CMM users to perform 5-axis measurement on a 3-axis co-ordinate measuring machine (CMM). It measures 1000s of points/sec and operates at speeds up to 500 mm/s. As the head is much lighter and more dynamic than the CMM, it is able to quickly follow changes in the part geometry without introducing harmful ...

  • Distributed Measurements Unlock the Future of Design

    The next generations of materials and design will require sensing technologies that can monitor beyond the scope of point sensors such as thermocouples and strain gauges. New sensing platforms based on optical fibers can obtain spatially continuous, real time data, giving developers detailed insight across broad areas into how their materials and designs behave. Such systems also can sense ...

  • Optical encoders and LiDAR scanning

    Overview Modern technology is taken for granted; a driver only needs to type a destination into a SATNAV system and step-by-step instructions, journey distance and duration, driving conditions and hazards, as well as alternative routes, instantly appear. In order to work, highly accurate and up-to-date maps are required of an entire country's road ...

  • Where do you find the latest meteo technologies at one place?

    Sustainability is the main theme of both the Meteorological Technology World Expo and the CIMO Teco (Technical Conference on Meteorological and Environmental Instruments and Methods of Observation)  held in Madrid from September 27 until 29, 2016. Therefore it’s the optimal platform to present one of our latest environmental sensor developments to a broad public: the ...

  • Surface flows from images: ten days of observations from the Tiber River gauge-cam station

    Fully remote surface flow measurements are crucial for flow monitoring during floods and in difficult-to-access areas. Recently, optics-based surface flow monitoring has been enabled through a permanent gauge-cam station on the Tiber River, Rome, Italy. Therein, a system of lasers and an internet protocol camera equipped with two optical modules afford video acquisitions of the river surface ...

  • Ping-Ping, What’s That Sound? Acoustic Fiber Optic Technology Helps Identify Problematic Water Mains

    With the deteriorating state of many aging water mains found in cities across North America, urbanites are frequently witnessing unexpected plumes of water erupt as man-made geysers in their own metropolitan backyards. While natural geysers are awe inspiring, urban geysers are much less so, due to their destruction to property, roads and the environment. Because an uninterrupted water flow is the ...
