OPI-210   Optical Flicker Test System

Calculate the highest percent flicker and flicker index by measuring average optical power of lamp


  • Technical Specifications
  • * Photo diode : silicone photodiode, effective section area :100mm2, Mismatching factor : f1’<1.5% Class L

    * Equipment Sampling Rate : 5 kHz

    * Calculate Flicker Index and Percent Flicker


     

  • Measurement algorithm

    a. Frequency: Detect frequency using fourier transform

    b. Percent flicker: 100 X ( A B ) / ( A + B )

    c. Flicker index : Area1 / ( Area1 + Area2 )
