Latest Build of LightSpace has a feature for iD3 users that is not available at any other software this time.
You can now manually set the integration time to any value....1.56....2.32...etc with editing the integration time value box, rather than using the LightSpace Intergration Time Slider.
This, according to X-Rite, will help with plasma profiling.
So, if you know the PWM Rate of the source you can set the integration time exactly... to do this:
1. Set the integration time to be an integer multiple of the PWM frequency of the corresponding display.
2. So, as an example, in PWM-based Display (Pioneer KURO with 24p signal), the frequency of the panel is 71.93Hz (PureCinema In Advance Mode) so the integration time should be an integer multiple, i.e., n*1/71.93Hz so if n were 100 then we obtain the following:
integration time to be = 100*1/71.93 = 1.39 seconds.
The more accurate you set, the better will be the results, gaining more stable repeatability
If you need to practice with different integer multiplier, there is a Measure & Log feature of LightSpace that it exports to an Excel file all your readings, xyY + the actual meter measuring time in ms. of each reading (3800ms, 5430ms.. etc).
