Light Source Fluxuations
Name: Ying Ying Ken Chu
What causes fluctuations in a light source?
This is a very general question. Do you have a specific fluctuation in
The most significant variation would be due to voltage variations. For
example, a fluorescent light generates light that fluctuates at 120 Hz
(60 Hz supply voltage). It varies from maximum intensity to nearly off
twice during each cycle.
