Semo-coherent? - What is definition
_hm   12/6/2014 7:06:10 AM

It is difficult to read LED semi-coherent light source. Is semi-coheren<-->LED defined by IEEE or OSA?

Or it is home grown deifnition to bias user in considering LED just another laser?

I like to know more about long term effect on health or other derivative symptoms.
