New acquisition system allows for simpler in vehicle operation, more powerful data capture and greater reliability.

San Diego, CA -- (SBWIRE) -- 06/18/2012 -- RoadVista, a Gamma Scientific company, has announced upgrades to the Laserlux® CEN 30 mobile retroreflectometer including a new data acquisition system. The Laserlux is used to quickly capture the retroreflectivity of pavement markings while traveling at highway speeds. The new acquisition system allows for simpler in vehicle operation, more powerful data capture and greater reliability.

Enhanced Data Acquisition for Improved Performance

Improved performance in the Laserlux data acquisition system is the result of upgrades to both the software and hardware of the instrument. RoadVista has added touch screen tablet PC compatibility to allow for simple in-vehicle operation of the Laserlux while driving. The sample rate is now at 200 kHz, allowing the device to capture more than 30,000 data points in a single 1.1 meter wide scan of the laser source. Scan resolution has also been upgraded to 16 bit, allowing the Laserlux to measure pavement markings from 0 to 4000 mcd/m2/lux with higher resolution than previous systems. Enhancements to the Laserlux's USB data acquisition result in even greater reliability. This upgrade is standard delivery with all new systems, and available for all existing Laserlux CEN 30 systems already out in the field.

"At RoadVista our team is constantly working to enhance the performance of our retroreflectometers," said Eric Nelson, RoadVista Product Manager. "Our new data acquisition system will further increase the Laserlux's industry leading accuracy and reliability, while also providing compatibility with the rapidly growing tablet market."

Real-Time Pavement Marking Retroreflectivity Measurements

The Laserlux CEN 30 mobile retroreflectometer contains proven optical measurement technology that objectively measures the retroreflectivity of pavement markings using a scanning laser source. Measurements are collected quickly and accurately by incorporating new, high-speed data acquisition electronics and software. The Laserlux provides real-time pavement marking reflectivity and can be used either day or night at variable traffic speeds.

Laserlux Mobile Retroreflectometer Features

- Utilizes ASTM E1710 and CEN 30-meter geometry with more than six inches of ground clearance
- Computer-controlled USB acquisition
- Real-time high speed measurements
- Scanning width of 1.1 meters
- WAAS-enabled GPS gives exact vehicle location with stripe data

System is optimized for quick testing of retroreflective materials to ensure ASTM E1709 requirements for safety testing. Benchtop four-axis retroreflectivity goniometer system for testing sign sheeting and high visibility clothing.

San Diego, CA -- (SBWIRE) -- 03/29/2012 -- RoadVista, a Gamma Scientific company, has announced the official release of their Model 933 Retroreflectivity Goniometer system for testing sign sheeting and high visibility clothing. The benchtop four-axis goniometer system serves as an inspection Quality Assurance (QA) instrument for quickly testing retroreflection at multiple measurement geometries.

The 933 retroreflectivity system measures retroreflection (RA) and the retroreflective color of materials. A 3-axis motorized goniometer features continuously adjustable ss1 (-60° to 60°), ss2 (-60° to 60°), and e (-180° to 180°) angles. The goniometer system also has a motorized, continuously adjustable a (0.2° to 2°) angle mechanism and color detector with observation angle fixed at 0.33°.

The primary light sensor for the 933 meets ASTM E1709 requirements with the CIE standard human eye response in conjunction with the CIE illuminant "A" lamp. The photometric detector accurately measures different colors without the need to calculate correction factors, while its color detector accurately calculates the CIE1931 color coordinates.

Powerful Data Capture and Intuitive Design

Operating as a stand-alone system, the 933 System can store readings and accompanying data for more than 30,000 measurements in non-volatile flash memory. Additionally, it can be controlled over USB via simple ASCII commands to automate multi-measurement requirements. USB drivers are available for Windows, Mac and Linux, along with sample Windows software utilizing Excel that demonstrates macro control.

The 933 features a high resolution color touch screen that is optimized to clearly render text and images for easy viewing of pertinent data. A separate graphics co-processor provides quick, intuitive responses.
