GL Opticam 3.0 road lighting quality measurement

Road lighting luminance measurement using the new imaging luminance meter, GL Opticam 3.0

Poznan University of Technology performed luminance measurements using GL Opticam 3.0 - the first imaging luminance measurement system fully adapted to the field work.

Poznan University of Technology, which has many years of experience in working with luminance meters, performed luminance measurements using GL Opticam 3.0 – the first fully adapted system to work in the field. While verifying the quality of road lighting of selected sections on the M class roads, the European made Imaging Luminance Measuring Device GL Optic was used.

During the measurements, the ILMD was used together with a unique set of accessories that facilitate and significantly speed up the determination of the measuring field, i.e. active markers, professional tripod, measuring wheel and a battery pack. The system also includes special wheeled transportation cases that allow to create a stable operator’s desk with a laptop. Dedicated GL Opticam SOFT software facilitates measurements and allows an immediate analysis of the lighting installation compliance with EN 13201 Road Lighting Standard.

“This is an extremely well thought-through system that was designed by GL Optic within a joint project with the Poznań University of Technology co-financed by National Centre for Research and Development in Poland (NCBiR). University of Technology employees have carried out many luminance measurements on expressways and in cities, and have supported this project with their experience and expert knowledge” comments PhD. Ing. Krzysztof Wandachowicz, the head of the Electrical Engineering and Electronics Institute at the Poznań University of Technology.

Apart from the modern measuring system, the meter is equipped with a hermetic housing, a battery set and a car converter (available upon customer’s request) which is a simple addition, yet when working in the field, where the measurements are often performed on closed road sections with no access to the AC power, it is a significant convenience. The set has been provided with all the necessary cables, and even screwdrivers and reflective vests.
Comparative studies have shown that the measurement accuracy of the set equals other devices from leading global providers. On the other hand, the repeatability of measurements, due to temperature stabilization, as well as the refined set of accessories and intuitive software outweigh all the instruments available for measuring luminance on the market.

The first field application imaging luminance meter uses a high resolution monochrome CMOS sensor (9 MP), a V-lambda (f1 ‘) filter in class A, RFID for automatic identification of optical accessories, temperature stabilized sensor, and the exposure time range from 50 s to 10 s. The accuracy and reliability of the data is ensured by a 9-step factory calibration, which is carried out in the GL Optic Optical Radiation Laboratory – the only unit in Central and Eastern Europe equipped with the Black Body Radiator – the primary standard source for implementation of spectral irradiance units. These types of reference standards are found only in the leading National Institutes of Standards and Technology in the world, such as NIST, PTB or VNIIOFI.
