Product description and applicable:
The GMS-1000 glare measurement system adopts a high-precision imaging luminance meter. It is good to test UGR ,TI,GR , used in Indoor and outdoor light pollution test.The high-precision measurement and analysis of the unified glare index UGR is realized through a precision electronically controlled pan/tilt and special measurement and control software. The measurement stability is good, the speed is fast, and the system is small in size and light in weight. . The system comes with a battery, no external power supply is required, and can be tested by connecting a USB cable to a computer.
Main technical features:
1. Use a high-precision imaging luminance meter to accurately measure the brightness of each point in the lighting scene, and calculate the glare index according to the theoretical formula.
2. The brightness measurement is as low as 0.001cd/m2, and the multiple exposure technology is adopted to obtain high dynamic images (HDR), which can accurately measure indoor and outdoor environments.
3. This system uses a precision pan/tilt to drive the imaging luminance meter for multi-angle testing, which eliminates the problem of high distortion when measuring a large field of view with a fisheye lens, and can achieve full-space low-distortion brightness image measurement up to 2π.
4. Whether the acquired brightness image is close to the center of the field of view of the observation angle or the peripheral area, the high resolution and high angular accuracy are maintained, and the problem of low resolution around the fisheye lens is better avoided.
