LMT OPTICAL FLICKER UNIT
Measurement system for visual aspects of temporal lighting artefacts
The LMT® Flicker measurement system can be used on an optical bench or as part of LMT® goniophotometer or integrating sphere laboratory equipment.
Features
- Very fast photometric signal acquisition (0.5 MHz over-sampling) with a final bandwidth of 10 kHz
- Firmware for online evaluation of
- Flicker Index and
- PercentFlicker
- Optional software application “SoLiT Flicker” reporting
- raw data of 10 fundamental modulation periods
- Flicker Index (= deviation from average)
- Percent Flicker (= modulation depth)
- FFT determination of modulation frequency (resolution 0.1Hz)
- Contour plot of acceptability ratings acc. to Bullough et al (Lighting Res. Technol. 2012; 44:477–483)
- Results acc. to technical note from CIE TC2-89
